Value Collection 011355P Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 011355P is a hex socket cap screw designed for high-strength fastening applications in mechanical assembly, tooling, and industrial maintenance work. It features a 1/2-13 UNC thread size with a 1-inch length under the head and is fully threaded from tip to head. Driven by a 3/8-inch hex key, this fastener is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces galling during installation. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for applications where high tensile strength and precise thread engagement are required.

This screw is suited for use in machinery, jigs, fixtures, hydraulic components, and structural assemblies where a flush or recessed fastener head is preferred. The 1/2-13 UNC coarse thread pattern offers good thread engagement in steel, cast iron, and aluminum tapped holes. Machinists, millwrights, maintenance mechanics, and industrial contractors commonly install this type of fastener in both shop and field settings. It is sold in a minimum order quantity of 50 pieces per order.

Key Features

• 1/2-13 UNC coarse thread for reliable engagement in standard tapped holes
• Fully threaded along the entire 1-inch length under head
• 3/8-inch hex drive for use with standard hex keys and socket drivers
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish reduces light reflection and provides light corrosion resistance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for tapped holes requiring a 1/2-13 UNC thread form in industrial, mechanical, and structural assemblies.

Installation Notes

Installation requires a 3/8-inch hex key or socket driver; ensure the drive tool is fully seated before applying torque to prevent rounding the socket. Power down and de-energize any machinery before fastener replacement on live equipment. Threads should be inspected for contamination or damage before installation, and appropriate thread lubricant or anti-seize may be applied per the assembly specification. Follow applicable industry standards and equipment manufacturer guidelines for proper seating and torque procedure.
