Key Features & Benefits at a Glance

  • Superior corrosion resistance for extended service life in marine and harsh industrial environments
  • High tensile strength of 70,000 psi ensures reliable load-bearing capacity and joint integrity
  • Rockwell B70 hardness provides excellent durability and resistance to deformation under stress
  • Fine UNF thread pattern (3/8"-24) delivers superior vibration resistance and precise fastening control
  • Class 2A thread fit guarantees consistent installation and compatibility with standard nuts
  • External hex drive design enables high-torque application with common industrial tools
  • Full threading along 7/8" length maximizes grip range and adjustment flexibility

Professional Applications & Engineering Value

Engineered for demanding applications where corrosion resistance and mechanical strength are critical, these 651 Silicon Bronze hex head screws solve common failure points in marine hardware, chemical processing equipment, and offshore structures. The UNF fine thread configuration maintains clamping force under vibration, while the external hex drive accommodates high installation torque without stripping. With 70,000 psi tensile strength and Rockwell B70 hardness, these fasteners prevent stress corrosion cracking and galling in saltwater environments, offering engineers a reliable alternative to stainless steel where superior corrosion performance is required.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 dimensional standards with Class 2A thread fit tolerances for consistent mating with standard components. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries. The 3/8"-24 UNF fine thread maintains precise pitch control while the external hex drive and right-hand thread direction follow industry-standard installation practices.
