Value Collection 011179P Hex Socket Cap Screw 1/4-28 Unf

Product Description

The VALUE COLLECTION 011179P is a hex socket cap screw designed for applications requiring a precise, high-strength fastener with a low-profile head. Threaded 1/4-28 UNF, it features fine-pitch threading for superior holding strength in metal-to-metal assemblies. The 7/8-inch length under head and 3/16-inch hex drive socket are machined to ASME/ANSI B18.3 and ASTM A574 standards. Constructed from alloy steel with a black oxide coating, this screw resists corrosion and reduces light reflection in service environments. It is fully threaded along its usable length, eliminating grip-zone gaps in thin-material stack-ups. Technicians, machinists, and maintenance professionals reach for this fastener in precision mechanical assemblies.

This screw fits residential and commercial mechanical, HVAC, electrical enclosure, and general industrial assembly applications where fine-thread fasteners are required. The 1/4-28 UNF thread pattern is common in applications calling for vibration-resistant joints or installations into tapped holes in aluminum, steel, or cast components. The black oxide finish suits both indoor and light-duty outdoor use where surface aesthetics and minimal corrosion protection are needed.

Key Features

• 1/4-28 UNF fine-thread pattern for strong engagement and vibration resistance
• Fully threaded shank along the 7/8-inch length under head
• 3/16-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide coating reduces corrosion and minimizes surface glare
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 1/4-28 UNF hex socket cap screw for use in any application or assembly specifying ASME/ANSI B18.3 socket head cap screws in that thread size and length.

Installation Notes

Installation is performed by machinists, maintenance technicians, or trade professionals using a 3/16-inch hex key or socket bit driver. Ensure the tapped hole is clean and free of debris before driving the fastener. Do not exceed the rated torque range for the fastener grade and base material. Power down or de-energize any equipment before servicing fastened assemblies on live electrical or mechanical systems.
