Professional Applications & Engineering Value

This M8 x 1.25mm nylon tip hex socket set screw delivers critical engineering solutions for industrial applications where vibration-induced loosening compromises assembly integrity. The 18-8 stainless steel body provides excellent corrosion resistance while maintaining Rockwell B80 hardness for durable thread engagement. The coarse thread pitch enables rapid installation in production environments, while the nylon 6/6 plastic tip creates consistent friction locking without damaging shaft surfaces. Ideal for precision machinery, automotive components, and electrical enclosures, this headless set screw maintains clamping force through thermal cycles from -50° to 250°F, solving common fastening challenges in manufacturing and maintenance operations.

Specification Summary & Compliance

This metric set screw features M8 x 1.25mm coarse threads with Class 6g tolerance for precise fitment. Manufactured to ASME B18.3.6M specifications with 4mm hex drive and 25mm length. The nylon tip measures 2.4mm in length and 4.8mm in diameter. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe use across global markets.
