Professional Applications & Engineering Value

This 1/4"-20 UNC hex head screw in 316 stainless steel delivers exceptional durability where corrosion resistance is critical. The coarse thread design prevents seizing in high-vibration industrial equipment, while the external hex drive enables secure tightening in confined spaces. With a 70,000 psi tensile strength, it withstands mechanical stress in structural assemblies, marine hardware, and chemical processing systems. The fully threaded configuration ensures uniform clamping force, reducing point failures in demanding applications where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 specifications with UNC Class 2A thread fit for precise dimensional accuracy. The screw features a 1/4"-20 coarse thread with right-hand direction and meets RoHS 3 (2015/863/EU) compliance for environmental safety. All measurements adhere to the inch system, including head width of 7/16" and length of 9/16", ensuring interchangeability and consistent performance in standardized assemblies.
