Performance & Construction
Socket head cap screws feature a high cylindrical head with a recessed hex drive, delivering strong engagement under high torque loads. The 18-8 stainless steel composition provides corrosion resistance for general construction, mechanical assembly, shop fabrication, and outdoor-exposed environments. Fully threaded shanks increase grip throughout the joint, while coarse threading allows easier assembly, improved performance in brittle materials, and compatibility with thicker coatings.

Application Use Cases
Suitable for machine assembly, equipment repair, shop fabrication, metalworking fixtures, and any application requiring reliable hex socket head fasteners. Designed for installation into pre-tapped holes or mating nuts to form a secure mechanical connection.

Quality & Reliability
All dimensions reflect real product measurements for accurate planning and repeatability. Full threading, consistent head geometry, and corrosion-resistant stainless construction support long-term reliability and align with professional user expectations for durability and precision.
