Polymer tool tethering attachment for screwdrivers, allen keys, and any parallel-shafted tool between 3.9mm and 9mm in diameter. The patented SoftLock core grips the tool shaft from the inside. The outer green ring rotates freely through 360 degrees, carrying the lanyard connection without absorbing any of the tool's rotation. Fitted in seconds with no tools. Non-metallic throughout, making it the correct choice for live electrical work, ATEX environments, and any area where metal components are restricted.
How the Rotating Outer Ring Solves the Screwdriver Tethering Problem
A fixed tether attachment on a screwdriver shaft transfers every turn of the driver directly into the lanyard cord. After a few rotations the lanyard is coiled tight, restricting tool movement and loading the attachment in a way it is not rated for. The Spin Tether solves this with a two-part construction: the inner black body grips the shaft and rotates with the tool, while the outer green ring stays free to rotate independently and carries the lanyard connection. The tool spins; the lanyard stays straight. No torque reaches the cord regardless of how many turns the screwdriver makes.
Key Features
Patented SoftLock core: Grips the tool shaft without damaging the surface, using advanced polymer technology rather than metal threads. Universal fit covers any parallel shaft from 3.9mm to 9mm in diameter. One product, no adapters.
Full 360-degree rotation: The outer ring and lanyard connection point are mechanically independent from the inner body. The tool rotates freely in any direction without winding or loading the lanyard.
Non-metallic construction: No metal components anywhere in the product. Suitable for use near live electrical conductors, in ATEX-classified explosive atmospheres, MRI-adjacent environments, and any area where metal is restricted or could cause a spark risk.
Finger-tight installation only: Loosen anti-clockwise, slide the shaft through, tighten clockwise to finger tight. No tools. No torque wrench. No risk of cracking the polymer body through over-tightening. Retrofittable to any compatible tool already in use on site.
Load rating moulded into the product: The 0.5kg max load is permanently moulded into the green outer ring. It cannot peel, fade, or be separated from the product.

Who Is This For
The Spin Tether is used by workers who carry screwdrivers, allen keys, or similar parallel-shafted rotating tools at height and need a tether that does not interfere with the tool's use. An electrician installing panel fixings from a MEWP, a maintenance engineer tightening bolts on elevated equipment, or a rope access technician with a set of screwdrivers on a telecoms mast all need the tool to rotate freely throughout the task. Where the working environment is live electrical, ATEX, or metal-sensitive, the non-metallic construction makes the Spin Tether the only appropriate choice in the NLG range.
Typical Applications
-
Tethering flathead, Phillips, Pozidriv, and Torx screwdrivers at height where the tool is in constant use and must rotate freely throughout the task.
-
Securing allen keys and hex keys at height on maintenance, installation, and commissioning work on elevated equipment.
-
Providing a non-metallic tether attachment for electricians working near live conductors where all fittings must be non-conductive.
-
Compliant tool tethering in ATEX-classified areas on oil, gas, petrochemical, and grain storage sites where metal-to-metal spark risk is a live concern.
-
Retrofitting a tether point to screwdrivers already issued to a team, without removing tools from service for modification.
How to Use
Step 1: Hold the Spin Tether with the green outer ring at the bottom. Rotate the two black sections in opposite directions, turning anti-clockwise, to loosen the SoftLock core and open the central aperture.
Step 2: Slide the tool shaft through the larger lower hole. Rotating the tool gently as you push it through reduces friction and makes the process easier.
Step 3: Tighten the black sections by rotating in opposite directions, turning clockwise, until finger tight. Do not over-tighten. The SoftLock core provides grip at finger-tight pressure. Using tools or excessive force will crack the polymer body.
Step 4: Test the tether point before putting the tool into use at height. Pull firmly to confirm the Spin Tether is correctly seated on the shaft.
Step 5: Connect an approved NLG lanyard to the green outer ring. The maximum lanyard length is 120cm. The green ring will rotate freely as the tool is used.
Common Mistakes
-
Over-tightening the black sections. Finger tight is sufficient. Applying a tool or excessive force damages the SoftLock core and cracks the polymer body, requiring replacement.
-
Fitting on a tapered or non-parallel shaft. The SoftLock core requires a parallel shaft between 3.9mm and 9mm to grip correctly. A tapered shaft will not seat the core evenly.
-
Using a lanyard longer than 120cm. The max lanyard length for the Spin Tether is 120cm, shorter than the 200cm standard for other NLG attachments. Check lanyard compatibility before use.
-
Using on tools over 0.5kg. A screwdriver heavier than 0.5kg requires the NLG Tether Ring or an alternative rated attachment.
-
Assuming non-metallic means no inspection is needed. Inspect the polymer body and green ring before each use for cracks, distortion, or surface damage, and retire if any are found.
Safety
The Spin Tether is rated to 0.5kg maximum load. Do not use on tools exceeding this weight. It is a tool tethering attachment only and must not be used as a personal fall protection component. Maximum lanyard length is 120cm. The product is suitable for live electrical, ATEX, and metal-sensitive environments due to its fully non-metallic construction, but users must confirm that the lanyard and anchor point used alongside it also meet the non-metallic or non-conductive requirements of the working environment. After any drop event, quarantine the Spin Tether and inspect before returning to service.
Maintenance
Inspect the polymer body and green outer ring before each use for cracks, distortion, or surface damage. Confirm the outer ring rotates freely. Check that the SoftLock core releases and re-grips smoothly when the black sections are rotated. Clean with a water-dampened cloth. Do not use solvents or aggressive cleaning agents on the polymer body. Store away from direct sunlight, heat sources, and sharp edges. Retire immediately if cracking, distortion, or loss of grip is visible.
Frequently Asked Questions
Q: What tools does the Spin Tether fit?
A: The Spin Tether fits any tool with a parallel shaft between 3.9mm and 9mm in diameter. This covers the full range of manual screwdrivers (flathead, Phillips, Pozidriv, Torx), allen keys, hex keys, pens, and styluses within the diameter range. It does not fit tools with tapered, fluted, or non-parallel shafts, and it is not designed for tools over 0.5kg.
Q: How does the 360-degree rotation work without tangling the lanyard?
A: The Spin Tether has a two-part construction. The inner black body grips the tool shaft via the SoftLock core and rotates with the tool when it is turned. The outer green ring is mechanically free to rotate independently from the inner body. The lanyard attaches to the green ring, which stays still while the inner body and tool turn inside it. No matter how many rotations the screwdriver makes, no torque reaches the lanyard.
Q: What does non-metallic mean in practice and why does it matter?
A: The Spin Tether contains no metal components at all. Every part is made from advanced polymer materials. This means it is safe to use near live electrical conductors where a metal attachment would present a shock risk, in ATEX-classified explosive atmospheres where metal-to-metal contact could generate a spark, and in MRI-adjacent or precision electronic environments where metal contamination or interference is a concern. Users must also confirm that the lanyard and anchor point they pair with the Spin Tether meet the same requirements for their specific environment.
Q: What do the safety standards mean?
A: The Spin Tether is certified to ANSI/ISEA 121-2023, the current international standard for dropped object prevention equipment, and NS 9611:2022+AC, the standard for personal tool attachment systems used at height. Dynamic testing at 2:1 safety factor means the product is tested at 1kg against its 0.5kg rating. CE and UKCA marking confirms UK and European safety compliance. Independent load test certificates and Declarations of Conformity are available from NLG on request.
Q: What is this product NOT suitable for?
A: It is not suitable for tools weighing more than 0.5kg. It does not fit tapered or non-parallel shafts. It is not recommended for power screwdrivers or cordless drivers where the high-speed spinning shaft could generate heat in the SoftLock core. It must not be used as a personal fall protection component. The maximum lanyard length is 120cm, shorter than the 200cm standard for other NLG attachments.
Q: What is the SoftLock core and how does it grip the shaft?
A: SoftLock is NLG's patented polymer grip technology built into the inner body of the Spin Tether. When the two black sections are tightened clockwise against each other, the SoftLock core compresses evenly around the tool shaft, creating a secure grip without damaging the shaft surface and without requiring metal threads or mechanical fasteners. The grip is achieved at finger-tight pressure only. Over-tightening does not improve the grip and will damage the polymer body.
Q: Can I use the Spin Tether on a cordless screwdriver or power driver?
A: The Spin Tether is not recommended for power drivers. The high-speed rotation of a power driver shaft generates friction heat that the SoftLock polymer core is not designed to sustain continuously. For cordless screwdrivers and drills, the NLG Tether Choke Single Arm or a specialist power tool tether is the correct solution.
