Value Collection 015167PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 015167PR is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and industrial equipment. It features a 1/4-20 UNC thread size, a 2.75 inch length under head, and a 3/16 inch hex drive socket. Manufactured from alloy steel and finished with a black oxide coating, this cap screw delivers corrosion resistance and reduced galling during installation. Licensed machinists, millwrights, and maintenance technicians use this type of fastener where a recessed drive and clean head profile are required.

This fastener is suited for use in precision mechanical assemblies, machine tool fixtures, jigs, and structural components where a flush or low-profile head is needed. The 1/4-20 UNC thread form is one of the most widely used coarse-thread standards in inch-based mechanical work, making this screw a common choice across manufacturing, maintenance, and fabrication environments. It installs with a standard 3/16 inch hex key or Allen wrench.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• 2.75 inch length under head with partial threading for clamping force in through-bolt applications
• 3/16 inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction for high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw conforming to ASME/ANSI B18.3 for use in any application requiring that thread size and drive configuration.

Installation Notes

Installation is performed with a 3/16 inch hex key or Allen-style driver. Ensure the mating tapped hole is clean and free of debris before threading. Do not exceed the rated torque range for 1/4-20 alloy steel cap screws as specified in applicable fastener standards. Apply thread-locking compound or fastener lubricant as required by the assembly specification.
