• High tensile strength of 140,000 psi provides dependable performance under heavy loads and stress conditions
• Space-saving low-profile design allows installation in confined spaces where standard socket heads won't fit
• Enhanced driving efficiency with hex drive system prevents cam-out and ensures secure tool engagement
• Full thread coverage along the entire length enables maximum grip and adjustment flexibility
• Regulatory compliance meets ASTM A574 specifications and environmental standards for global industrial use

Professional Applications & Engineering Value

These low socket head cap screws deliver critical engineering advantages where space constraints and precision matter most. The black-oxide alloy steel construction provides superior corrosion protection while maintaining Rockwell C39 hardness for wear resistance in high-cycle applications. The 10-32 UNF fine thread configuration offers enhanced clamping force distribution and superior resistance to vibrational loosening compared to coarse threads. Engineered for precision machinery, automotive assemblies, and electronic enclosures, these fully threaded fasteners ensure maximum thread engagement in thin materials and blind holes. The low-profile socket head design is particularly valuable in compact assemblies where standard socket protrusion would interfere with adjacent components, while the hex drive system guarantees reliable torque transmission without stripping.

Specification Summary & Compliance

Manufactured to ASTM A574 specifications with Class 3A thread fit for precision applications. Features UNF fine threads with right-hand direction and full threading along the 1/2" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black-oxide surface treatment on alloy steel substrate provides additional corrosion protection while maintaining dimensional stability.
