Value Collection 015175PR Hex Socket Cap Screw 1/4-28 Unf

Product Description

The VALUE COLLECTION 015175PR is a hex socket cap screw designed for precision fastening applications requiring a compact drive profile and high clamping strength. Manufactured from alloy steel with a black oxide finish, this fastener meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards. The 3/16-inch hex drive accepts a standard Allen key or hex bit driver, and the 1/4-28 UNF fine thread provides excellent thread engagement and resistance to vibration loosening. Fully threaded along the 5/8-inch length under the head, this screw delivers consistent clamping force across the entire grip range. It is well-suited for mechanical assemblies, equipment repair, and maintenance applications across HVAC, plumbing, and electrical trades.

This fastener is used in applications where a flush or low-profile socket-drive cap screw is required. The fine thread pitch of the 1/4-28 UNF designation makes it appropriate for installations in metal components where thread fit and torque control are critical, such as equipment panels, bracket mounting, valve assemblies, and motor housings. It is sold as a single-piece package with a minimum order quantity of 100 units, making it suitable for stocking by maintenance facilities, contractors, and trade shops that regularly service mechanical equipment.

Key Features

• 1/4-28 UNF fine thread for precise fit and vibration resistance
• Alloy steel construction for high tensile strength in demanding applications
• Black oxide coating provides moderate corrosion resistance and reduces light reflection
• Fully threaded 5/8-inch length under head for maximum thread engagement
• 3/16-inch hex (Allen) drive compatible with standard hex keys and power bit drivers
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies that require a 1/4-28 UNF hex socket cap screw with a 5/8-inch length under head.

Installation Notes

Install using a 3/16-inch hex key or hex bit driver rated for the torque requirements of the application. De-energize or shut down any equipment before accessing fastener locations on live electrical or pressurized mechanical systems. Follow applicable codes and equipment manufacturer torque specifications when seating cap screws in critical assemblies. Avoid cross-threading by starting the screw by hand before applying drive torque.
