Value Collection 011383P Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 011383P is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 1/2-13 UNC thread size with a 5-1/2 inch length under head and accepts a 3/8 inch hex drive. Constructed from alloy steel with a black oxide finish, this fastener resists corrosion and wear under demanding service conditions. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, ensuring consistent dimensional and mechanical performance. Machinists, maintenance technicians, and industrial assemblers use this screw where reliable clamping force and precise fitment are required.

This hex socket cap screw is suited for use in general industrial machinery, tooling fixtures, structural steel connections, and equipment frames. The partial threading allows the unthreaded shank to bear shear loads cleanly, making it a preferred choice in precision alignment applications. It is appropriate for both original equipment assembly and field repair situations where an ASME/ANSI B18.3-compliant socket cap screw is specified.

Key Features

• 1/2-13 UNC thread size with partial threading for shear load applications
• 5-1/2 inch length under head for deep fastening in thick material
• 3/8 inch hex drive for reliable torque transfer with standard hex keys or socket drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides mild corrosion resistance and reduces galling
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use wherever a 1/2-13 UNC partially threaded socket cap screw is specified in industrial and mechanical assemblies.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians using a calibrated 3/8 inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from the equipment manufacturer or applicable ASME standards. Do not use impact tools that may overtorque or damage the socket drive recess.
