Professional Applications & Engineering Value
This cadmium-plated steel hex head screw delivers exceptional reliability for demanding aerospace and industrial applications where vibration resistance and mechanical security are paramount. The Class 3A UNF fine thread configuration ensures precise fitment and superior clamping force distribution, while the integrated 1/16" cotter pin hole provides positive locking that prevents accidental loosening in high-vibration environments. The external hex drive facilitates efficient installation with common tools, and the partial threading design optimizes the strength-to-weight ratio. With 120,000 psi tensile strength and Rockwell C26 hardness, this fastener maintains structural integrity under extreme loads, making it ideal for critical assemblies requiring AN5-14 specification compliance.
Specification Summary & Compliance
This 5/16"-24 UNF hex head screw features Class 3A thread fit precision with 0.3125" thread diameter and fine thread spacing. The partially threaded design provides 1 1/16" grip length and overall 1 19/32" length. Manufactured to meet AN5-14 specifications with Rockwell C26 hardness and 120,000 psi tensile strength. Includes 1/16" cotter pin hole with 0.076" diameter for secure mechanical locking applications.
