Value Collection 011183P Hex Socket Cap Screw 1/4-28 Unf

Product Description

The VALUE COLLECTION 011183P is a 1/4-28 UNF hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, machinery, and fabrication work. The fastener features a 3/16-inch hex drive and measures 1-1/4 inches in length under the head. Constructed from alloy steel with a black oxide finish, it delivers solid tensile strength and a degree of corrosion resistance suited to industrial and shop environments. This screw is fully threaded along its length, making it appropriate for through-hole and close-tolerance clamping applications. Machinists, maintenance technicians, and industrial assemblers are the primary installers.

This cap screw is suited for use in general industrial assemblies, tooling fixtures, machine frames, and equipment maintenance scenarios where a UNF fine-thread fastener is specified. The fine 1/4-28 thread pitch provides stronger thread engagement per unit length compared to coarse-thread equivalents, making it well matched to applications involving vibration or thin-walled tapped holes. It meets ASME/ANSI B18.3 and ASTM A574 standards, confirming dimensional and mechanical compliance for professional trade use.

Key Features

• 1/4-28 UNF fine thread for tighter engagement and vibration resistance
• 3/16-inch hex socket drive for use with standard Allen keys and hex drivers
• Fully threaded shank for maximum thread engagement across the full fastener length
• Alloy steel construction for high tensile strength in demanding mechanical applications
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance

Compatibility

Designed as a standard 1/4-28 UNF hex socket cap screw for use in any application requiring ASME/ANSI B18.3-compliant socket head fasteners with a 3/16-inch hex drive.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 3/16-inch hex key or socket driver. Ensure the tapped hole is clean and free of debris before threading. Apply appropriate thread-locking compound or torque to specification per the equipment manufacturer's requirements. Do not overtighten in thin-walled or soft-material tapped holes, as the fine thread form can strip if excessive force is applied.
