• Environmentally responsible sourcing meeting RoHS 3 and REACH regulations for safe use in regulated industries

Professional Applications & Engineering Value

This M4 set screw delivers critical performance in precision assemblies where space is limited and vibration resistance is paramount. The alloy steel construction, hardened to Rockwell B67, provides excellent shear strength and prevents loosening under dynamic loads. The headless design and flat tip allow for flush mounting against shafts, collars, and pulleys, eliminating protrusions in machinery. Its metric coarse thread (M4 x 0.7mm) with Class 6g tolerance ensures quick assembly and a secure fit in tapped holes, reducing the risk of cross-threading. Ideal for securing gears, bearings, and other components in automotive, manufacturing, and automation equipment, this slotted set screw solves alignment and retention challenges while meeting strict DIN 551 and ISO 4766 standards for dimensional consistency.

Specification Summary & Compliance
