Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction and passivated finish, ideal for harsh environments and chemical exposure
- High tensile strength of 70,000 psi ensures reliable load-bearing capacity and structural integrity in demanding applications
- Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies with minimal backlash
- 3/4" hex drive socket head allows for high-torque installation and easy access in confined spaces with standard tools
- Partially threaded design combines unthreaded shank stability with threaded section grip for optimized clamping force distribution
- Compliance with RoHS 3 and REACH regulations guarantees environmental safety and unrestricted use in regulated industries
- Coarse 1"-8 UNC threads enable faster assembly and reduced cross-threading risks compared to fine-thread alternatives
Professional Applications & Engineering Value
Engineered for industrial fastening where corrosion resistance and mechanical reliability are critical, this 316 stainless steel socket head cap screw addresses common failure points in machinery, marine equipment, and chemical processing systems. The passivated finish enhances the innate corrosion resistance of 316 stainless steel, providing an extra barrier against chlorides and acidic environments. With its 1"-8 UNC coarse thread and Class 3A thread fit, it ensures rapid installation with minimal galling while maintaining precise alignment in high-vibration settings. The partially threaded configuration allows the unthreaded portion to act as a precision pilot, reducing stress concentration and improving fatigue life in dynamic load applications.
Specification Summary & Compliance
This socket head cap screw features a 1"-8 UNC coarse thread with Class 3A thread fit per ASME B1.1 standards, ensuring dimensional accuracy and interchangeability. The partially threaded design includes a minimum thread length of 2 1/2" on a 3 1/2" overall length. Material and finish comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety requirements for industrial components.
