Value Collection 011193P Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 011193P is a hex socket cap screw designed for industrial and mechanical fastening applications requiring a compact, high-strength connection. Manufactured from alloy steel with a black oxide coating, this screw features a 5/16-18 UNC thread and a 3/8-inch length under head with full threading along the shank. The 1/4-inch hex drive accepts a standard hex key or Allen-type bit. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for structural and machine assembly work where tensile strength and dimensional consistency are critical. Mechanical contractors, millwrights, and maintenance technicians commonly specify this fastener type across a wide range of equipment assemblies.

This screw is suited for use in machinery, fixtures, tooling, and mechanical assemblies where a flush or recessed drive is required. The 5/16-18 UNC coarse thread pattern provides reliable engagement in tapped steel, cast iron, and aluminum substrates. The black oxide finish offers mild corrosion resistance in low-moisture indoor environments. This part is ordered in multiples of 100, making it appropriate for production environments, MRO stocking, or field service kits requiring consistent quantities of a single fastener specification.

Key Features

• 5/16-18 UNC coarse thread for reliable engagement in standard tapped holes
• 3/8-inch length under head, fully threaded along the entire shank
• 1/4-inch hex socket drive compatible with standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 for high tensile strength requirements
• Black oxide coating provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards for consistent fitment

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 5/16-18 UNC threaded fastener with a 3/8-inch length under head and a 1/4-inch hex drive.

Installation Notes

Installation is performed using a 1/4-inch hex key or compatible Allen-type driver. Ensure the mating tapped hole meets 5/16-18 UNC thread specifications before installation. De-energize or lock out any machinery before fastener replacement or assembly work per applicable OSHA lockout/tagout procedures. Avoid overtightening, which can strip threads in softer base materials such as aluminum.
