Professional Applications & Engineering Value

Engineered for demanding industrial settings, this 1"-8 UNC hex head screw delivers critical reliability where failure is not an option. The 18-8 Stainless Steel material provides excellent resistance to rust and oxidation, making it suitable for outdoor, marine, or chemical-exposed applications. Its coarse thread design is particularly effective in softer materials or where rapid assembly is required, minimizing stripping and ensuring a secure hold. The fully threaded 8-inch shank offers versatile clamping across thick assemblies, from structural steel frames to heavy machinery. With an 80,000 psi tensile strength and external hex drive, it withstands high vibration and torque, reducing the need for frequent retightening and maintenance in heavy-duty operations.

Specification Summary & Compliance

This hex head screw adheres to UNC (Unified Coarse Thread) standards with a Class 2A thread fit for consistent, precision threading. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. The screw features a right-hand thread direction, is fully threaded, and is supplied in inch measurements, confirming its suitability for specifications requiring ASME or similar dimensional standards.
