Value Collection 011281P Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 011281P is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and industrial equipment. Manufactured from alloy steel with a black oxide finish, this screw provides corrosion resistance and reduced light reflection in service environments. The 3/8-16 UNC thread form is a standard coarse-thread specification widely used in North American fastener applications. Drive engagement is through a 5/16 inch internal hex socket, requiring a standard hex key or Allen-type driver. The screw measures 5 inches in length under the head and is partially threaded, making it suitable for clamping applications where a grip length is needed.

This fastener is suited for use in machine shops, manufacturing facilities, maintenance operations, and industrial assembly work. The alloy steel construction and black oxide coating make it a common choice for fixture plates, jigs, dies, and structural mechanical assemblies where tensile strength and a clean low-profile head are required. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, which define the dimensional and mechanical requirements for socket cap screws.

Key Features

• 3/8-16 UNC coarse thread form for compatibility with standard North American tapped holes
• 5 inches length under head with partial threading to provide a grip length for clamping joints
• Alloy steel construction meets ASTM A574 mechanical requirements for socket cap screws
• Black oxide finish provides mild corrosion resistance and reduced surface reflectivity
• 5/16 inch internal hex drive accepts standard hex keys and socket drivers
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

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

Installation Notes

Installation is performed using a 5/16 inch hex key or Allen driver. Ensure the mating tapped hole meets 3/8-16 UNC thread specifications and is free of debris before installation. Follow applicable torque guidelines from ASME or fastener manufacturer references for ASTM A574 socket cap screws in the applicable joint material. Always de-energize and lock out equipment before accessing fastened assemblies in powered machinery.
