- Class 2A thread fit provides consistent, smooth installation with standard UNC coarse threads, reducing cross-threading risks.
- Vented design with 0.093" diameter allows for pressure equalization, preventing fluid or gas buildup in sealed systems.
- External hex drive and hex head enable quick, secure tightening with common tools, speeding up assembly and maintenance.
- Partial threading offers optimal grip length for specific joint requirements, enhancing clamping force control.
- Compliance with RoHS 3 and REACH standards ensures environmental safety and regulatory acceptance in global markets.
Professional Applications & Engineering Value
This 3/8"-16 UNC hex head screw is engineered to address critical challenges in industrial fastening, where corrosion resistance and mechanical reliability are paramount. The 18-8 stainless steel material combats rust and chemical exposure in applications like machinery, marine equipment, and structural frameworks, extending service life. Its coarse thread design ensures rapid installation and vibration resistance, while the vented feature mitigates pressure differentials in pneumatic or hydraulic systems, preventing seal damage. With a Rockwell B70 hardness and 70,000 psi tensile strength, it withstands heavy loads and repetitive stress, making it a trusted choice for industrial fasteners in manufacturing, construction, and automotive sectors where durability and compliance with RoHS and REACH are essential.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 2A thread fit for precise dimensional accuracy and ease of assembly. Key specifications include a thread size of 3/8"-16, length of 1-1/2", and partial threading with a minimum thread length of 1". It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for regulated industrial use.
