Value Collection 015395PR Hex Socket Cap Screw 1/2-20 Unf

Product Description

The VALUE COLLECTION 015395PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 1/2-20 UNF thread size, a 1-1/4 inch length under head, and a 3/8 inch hex drive. Manufactured from alloy steel with a black oxide finish, it provides solid corrosion resistance and surface hardness suited to demanding environments. The fastener is fully threaded and conforms to ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it a recognized choice for precision mechanical work where torque retention and dimensional accuracy matter.

This cap screw is used across a wide range of trade and industrial applications including HVAC equipment assembly, pump and motor mounting, pipe support brackets, and general structural fastening. Its 1/2-20 UNF thread pitch is well suited to fine-thread applications where vibration resistance and precise clamping force are required. Licensed mechanics, millwrights, and field service technicians commonly use this fastener when servicing or assembling equipment that demands a consistent, spec-compliant socket head fastener.

Key Features

• 1/2-20 UNF fully threaded hex socket cap screw for fine-thread applications
• 1-1/4 inch length under head for consistent clamping depth
• 3/8 inch hex drive compatible with standard socket head Allen keys and drivers
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide coating provides corrosion resistance and reduces light reflection
• Compliant with ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 1/2-20 UNF fully threaded fastener with a 3/8 inch hex drive.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with fine-thread fastener procedures. Ensure mating threads are clean and free of debris before installation. Disengage power and relieve any system pressure before servicing assemblies that contain this fastener. Use a calibrated torque wrench with the appropriate 3/8 inch hex bit and follow the torque specifications of the equipment manufacturer, as no torque value is specified for this fastener in isolation.
