Secure clamping that prevents measurement drift

A compact fastener with an M8 thread offers reliable axial clamping for sliding measurement tools. By preventing unwanted movement, this type of locking screw reduces the risk of measurement error and rework, improving throughput in repetitive inspection tasks. The robust thread form ensures repeatable clamping torque, which translates into stable readings on precision calipers and other sliding gauges.

Easy adjustment and maintenance with standard tooling

The drive accepts a 4 mm Allen key, which simplifies assembly and on-site adjustments without special tools. The short 21 mm overall length makes the component ideal where space is limited, such as inside caliper heads or small fixtures. Maintenance cycles are faster because standard hex keys are widely available in workshops, lowering downtime and keeping measuring equipment in service with minimal effort.
