Professional Applications & Engineering Value

Engineered for precision shaft collars, pulley systems, and gear assemblies, this 5/16"-18 UNC set screw delivers exceptional vibration resistance through its Class 3A thread fit and 90° cone point design. The 18-8 stainless steel construction provides reliable corrosion resistance in manufacturing environments exposed to moisture or chemicals. The headless hex drive configuration enables flush mounting where protruding fastener heads would interfere with moving components. With coarse threading and Rockwell B80 hardness, this industrial set screw maintains clamping force under dynamic loads while resisting wear in high-cycle applications.

Specification Summary & Compliance

This 5/16"-18 UNC set screw features Class 3A thread fit precision with 0.313" thread diameter and 3/4" length. Manufactured to ASME B18.3 specifications with right-hand coarse threads and 5/32" hex drive. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
