Value Collection 011175P Hex Socket Cap Screw 1/4-28 Unf

Product Description

The VALUE COLLECTION 011175P is a hex socket cap screw designed for applications requiring a strong, compact fastener with a recessed drive. Manufactured from alloy steel with a black oxide finish, this screw provides corrosion resistance and a clean, low-profile appearance. The 1/4-28 UNF thread is a fine-pitch designation suited for tight-tolerance assemblies where vibration resistance and precise thread engagement matter. The 3/16 inch hex drive requires a standard Allen key or hex bit driver. Fully threaded along its 5/8 inch length under head, this fastener delivers maximum thread engagement across its full shank. Installers, machinists, and maintenance technicians working in mechanical, HVAC, or equipment assembly applications will find this screw a direct-fit solution for many standard 1/4-28 UNF tapped holes.

This socket cap screw is appropriate for light mechanical assemblies, equipment panels, bracket mounting, and precision-fit applications where a hex socket drive is specified. The fine UNF thread pitch suits applications in metal-to-metal fastening where standard coarse threads are not specified. The black oxide coating helps reduce surface rust in moderately dry environments and minimizes light reflection in exposed assemblies. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for engineered assemblies that specify conformance to those fastener standards.

Key Features

• 1/4-28 UNF fine-pitch thread for tight-tolerance and vibration-resistant assemblies
• Fully threaded shank maximizes thread engagement over the full 5/8 inch length under head
• Alloy steel construction provides strength suitable for structural and mechanical fastening
• Black oxide finish adds surface corrosion resistance and reduces light reflection
• 3/16 inch hex socket drive accepts standard Allen keys and hex bit drivers
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as a standard 1/4-28 UNF hex socket cap screw replacement or new-installation fastener for mechanical assemblies, equipment housings, and bracket applications requiring ASME/ANSI B18.3 and ASTM A574 compliant fasteners.

Installation Notes

Installation requires a 3/16 inch hex key or Allen-style bit driver. Confirm the mating tapped hole is cut to 1/4-28 UNF specification before driving. Power down or de-energize any equipment before accessing fastened assemblies in electrical or HVAC applications. Do not exceed the torque rating specified by the equipment manufacturer for this thread size and material class.
