Value Collection 011203P Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 011203P is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. This screw features a 5/16-18 UNC thread size with a 1-inch length under the head and is fully threaded from tip to head. It is driven by a 1/4-inch hex key. Constructed from alloy steel with a black oxide finish, this fastener delivers solid tensile strength and moderate corrosion resistance. Machinists, maintenance technicians, and fabricators install these in equipment assemblies, jigs, fixtures, and machine frames where a flush or recessed fastening point is required.

This fastener is suited for use in production environments, machine shops, and maintenance operations where UNC-threaded socket cap screws are a standard hardware specification. The 5/16-18 thread size is common in light-to-medium duty mechanical assemblies. Fully threaded geometry provides maximum thread engagement in thin materials and short-depth tapped holes. This part is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• 5/16-18 UNC fully threaded profile for maximum thread engagement
• 1-inch length under head suits standard depth tapped holes in medium-gauge materials
• 1/4-inch hex drive accepts standard hex keys and hex bit drivers
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish offers mild corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance

Compatibility

Designed as an OEM-style replacement or standard-stock socket cap screw for any application specifying a 5/16-18 UNC fully threaded hex socket fastener per ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is performed using a 1/4-inch hex key or hex bit driver. Verify that the mating tapped hole matches the 5/16-18 UNC thread specification before installation. De-energize or lock out any equipment before fastener replacement or assembly work per applicable safety procedures. Do not exceed the rated torque range for the alloy steel grade and fastener size as defined by your engineering specification or applicable ASME standards.
