Professional Applications & Engineering Value
This M8 set screw is engineered to solve critical challenges in industrial assembly and machinery. The hardened alloy steel body and Rockwell C45 rating deliver exceptional resistance to vibrational loosening and fatigue, making it ideal for securing gears, pulleys, and collars on rotating shafts. The coarse thread (1.25mm pitch) and Class 5g6g tolerance enable rapid installation and a secure fit in both through-holes and blind tapped holes, reducing the risk of cross-threading. The cup tip concentrates pressure on a small contact area, creating a permanent locking point that maintains alignment in high-stress environments. This combination of material strength and precision thread form ensures reliable performance in automotive, manufacturing, and heavy equipment applications where failure is not an option.
Specification Summary & Compliance
This metric set screw conforms to DIN 916 / ISO 4029 specifications, ensuring dimensional accuracy for the M8 x 1.25mm coarse thread with a Class 5g6g thread fit. The product is manufactured from Alloy Steel and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industrial markets.
