Value Collection 011305PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 011305PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and industrial equipment. It features a 3/8-24 UNF thread size, a 3-inch length under head, and a 5/16-inch hex drive. Constructed from alloy steel with a black oxide coating, it provides solid corrosion resistance in controlled environments. The partial threading pattern allows for precise clamping force when fastening into tapped holes. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it a dependable choice for applications where mechanical strength and dimensional consistency are required.

This screw is suited for use in machine shops, fabrication environments, and maintenance operations where fine-threaded fasteners are specified. The 3/8-24 UNF thread pitch is commonly used in precision assemblies, tooling fixtures, and equipment where finer thread engagement is needed compared to UNC alternatives. Licensed machinists, millwrights, and maintenance technicians typically install this style of fastener in both light and heavy industrial settings.

Key Features

• 3/8-24 UNF thread for fine-thread engagement and precise clamping
• 3-inch length under head for deeper fastening reach
• 5/16-inch hex drive compatible with standard hex keys and Allen wrenches
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides moderate corrosion resistance and reduces light reflection
• Partially threaded shank allows for controlled clamp load in through-bolt and tapped-hole applications

Compatibility

Designed as an OEM-style replacement or general-use hex socket cap screw for applications specifying 3/8-24 UNF partially threaded fasteners conforming to ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation should be performed by qualified machinists or maintenance technicians familiar with fine-thread fastener practices. Use a properly sized 5/16-inch hex key or socket driver to avoid rounding the drive recess. Verify that the mating tapped hole conforms to 3/8-24 UNF thread specifications before installation. Follow applicable industry and facility standards for fastener preload and torque procedures appropriate to the assembly.
