- Space-saving headless design allowing flush mounting where clearance is limited
- Industry-standard compliance meeting ASME B18.3 specifications for guaranteed interchangeability
Professional Applications & Engineering Value
This 8-36 UNF Class 3A set screw delivers critical engineering solutions for precision assemblies requiring permanent component positioning. The fine thread configuration provides superior resistance to vibrational loosening in rotating machinery, while the cup point design creates permanent dimples in shafts for maximum torque transmission. Manufactured from 18-8 stainless steel, it maintains integrity in corrosive environments common in automotive, aerospace, and manufacturing equipment. The headless hex drive configuration enables installation in confined spaces where traditional fasteners cannot operate, making it ideal for coupling collars, gear hubs, and precision instrument assemblies demanding reliable set screw performance without protrusion interference.
Specification Summary & Compliance
This precision fastener features 8-36 UNF fine threads with Class 3A thread fit for tight tolerance applications, measuring 0.164" thread diameter and 3/8" length. Manufactured in compliance with ASME B18.3 standards for dimensional consistency and mechanical properties. The product is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental regulations for hazardous substance restrictions.
