• Black finish for corrosion resistance
• Right-hand thread for standard fastening

Perfect For

• AR-15 and AR-10 component assembly
• Precision firearm builds requiring exact torque specs
• Replacement hardware for upper and lower receivers
• Custom builds where fastener reliability matters

Socket Head Cap Screw Design

The cylindrical socket head design concentrates force directly into the internal hex drive, eliminating the slipping and rounding that occurs with external drives. This matters because precision builds require consistent torque application without guesswork. The 1/2" length positions this screw for critical connection points in receiver assembly and component mounting where depth control is essential.

Black Finish and Material Durability

Black finish provides corrosion protection in humid environments and reduces light reflection during operation. The finish also maintains consistency across mixed hardware setups where appearance matters alongside function. For builders working with anodized receivers or coated parts, the black finish integrates visually without requiring additional finishing work.

Thread Specification and Compatibility

The 10-32 UNF specification uses fine threads, which means tighter spacing and more engagement points per rotation than coarse threads. This creates stronger holding power in materials like aluminum and polymer. Right-hand threads follow standard fastening convention, eliminating confusion during assembly and ensuring compatibility with standard tapping and receiver holes.
