Value Collection 011287PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 011287PR is a hex socket cap screw designed for high-strength fastening in mechanical, industrial, and trade assembly applications. It features a 3/8-24 UNF thread and measures 3/4 inches in length under the head. The screw is fully threaded, driven with a 5/16-inch hex key, and manufactured from alloy steel with a black oxide finish. Black oxide provides moderate corrosion resistance and reduces light glare in finished assemblies. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding load-bearing installations. Machinists, maintenance technicians, and mechanical contractors commonly use this type of fastener in equipment assembly and structural component attachment.

This cap screw is suited for use in close-tolerance assemblies where a flush or recessed head profile is required. The 3/8-24 UNF fine thread provides greater tensile strength and finer adjustment than coarse-thread equivalents, making it a preferred choice in applications involving vibration, precision machinery, or thin-walled components. Typical install scenarios include machine frames, brackets, fixtures, and mechanical subassemblies across industrial, HVAC equipment, and general maintenance environments. Minimum order quantity is 100 pieces.

Key Features

• 3/8-24 UNF fine thread for high tensile strength and vibration resistance
• Fully threaded shank maximizes thread engagement along the full fastener length
• 5/16-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides moderate corrosion protection and low-glare appearance
• 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 3/8-24 UNF fully threaded fastener with a 5/16-inch hex drive.

Installation Notes

Installation should be performed by a qualified technician or machinist familiar with fastener torque requirements for alloy steel cap screws in the applicable assembly. Ensure the mating threaded hole or nut meets the same thread specification (3/8-24 UNF) before installation. Use a calibrated torque wrench or driver to reach the manufacturer- or engineering-specified clamp load for the application. Do not mix thread standards or use damaged threads, as this compromises joint integrity.
