Professional Applications & Engineering Value

These 10-24 UNC coarse thread screws provide critical solutions for industrial assembly challenges where vibration resistance and corrosion protection are paramount. The zinc-plated steel construction offers excellent durability against environmental factors while maintaining the 60,000 psi tensile strength required for heavy-duty applications. The rounded head design with one-way drive prevents unauthorized removal in security-sensitive installations, making them ideal for machinery, electrical enclosures, and structural frameworks. The fully threaded configuration ensures maximum thread engagement across the entire length, distributing load evenly and preventing loosening under dynamic stresses. Engineered to ASME B18.6.3 specifications, these fasteners deliver consistent performance in automotive, manufacturing, and construction applications where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading (10-24 size) in the inch measurement system. The screws feature a standard rounded head profile with 0.359" diameter and 0.137" height, providing optimal bearing surface. Full compliance with ASME B18.6.3 manufacturing standards ensures dimensional accuracy and interchangeability. Environmental certifications include RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) compliance for chemical safety management, making these screws suitable for global industrial distribution and use.
