Professional Applications & Engineering Value

This M1 x 0.25 mm metric screw is engineered to address critical challenges in precision engineering and electronics assembly. Its 18-8 stainless steel material, enhanced by a passivated finish, provides excellent resistance to oxidation and chemical exposure, making it ideal for medical devices, instrumentation, and telecommunications equipment where reliability is non-negotiable. The rounded cheese head with a slotted drive and narrow profile facilitates easy access and installation in compact assemblies, reducing assembly time and tooling complexity. With a fully threaded design and Class 6g thread fit, it ensures uniform load distribution and prevents cross-threading, a common failure point in fine-pitch metric coarse thread applications. This screw delivers consistent performance, minimizing downtime and maintenance costs in high-precision industrial settings.

Specification Summary & Compliance

This precision screw adheres to Class 6g thread fit tolerances as per ISO metric standards, ensuring dimensional accuracy for the M1 x 0.25 mm thread size and 8 mm length. It is manufactured in compliance with DIN 84 and ISO 1207 specifications for rounded head slotted screws. The product fully meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, confirming its safety for use in various international markets without hazardous substances.
