Professional Applications & Engineering Value

This 3/8"-16 UNC hex head screw delivers critical sealing performance where standard fasteners fail. The silicone rubber O-ring creates a reliable barrier against fluid and gas penetration, solving leakage issues in high-pressure systems up to 20,000 psi. Manufactured from 18-8 stainless steel, it maintains structural integrity in corrosive environments while the coarse UNC thread provides rapid installation in production settings. The external hex drive accommodates high torque requirements for secure assemblies in industrial equipment, hydraulic systems, and processing machinery where pressure integrity is paramount. With operating temperatures from -80° to 400°F, this sealing screw performs consistently across extreme thermal cycles.

Specification Summary & Compliance

This fully threaded hex head screw features 3/8"-16 UNC coarse threads with Class 2A thread fit for precise dimensional accuracy. The 5/8" length and 0.375" thread diameter conform to standard specifications with maximum hole diameter compatibility of 0.399". Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental responsibility and regulatory adherence for global industrial applications.
