Professional Applications & Engineering Value
This M8 shoulder screw delivers critical engineering value in precision assemblies where alignment and rotational control are paramount. The 16mm shoulder length with tight diameter tolerance acts as a precise pivot or spacer, eliminating misalignment in machinery, automotive, and electronic enclosures. Manufactured from 18-8 stainless steel, it resists oxidation and chemical exposure, ideal for food processing, marine, or outdoor equipment. The coarse metric thread (M8x1.25mm) and Class 5g6g thread fit provide rapid installation and secure holding in soft materials or high-vibration settings. Combined with the hex socket drive and knurled head, it ensures tool engagement without slippage, reducing assembly time and maintenance costs in automated production lines.
Specification Summary & Compliance
This shoulder screw maintains ISO 7379 dimensional standards with a Class 5g6g thread fit for consistent interchangeability. Shoulder diameter tolerance is controlled between -0.072 to -0.01 mm, and shoulder length tolerance from 0 to 0.25 mm, ensuring precise assembly fits. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it is free from hazardous substances for safe use in regulated industries.
