Value Collection 581369P 1/4-20 Unc Socket Cap Screw Alloy Steel

Product Description

The VALUE COLLECTION 581369P is a hex socket cap screw designed for applications requiring a compact, high-strength fastener with a low-profile head. Built from alloy steel with a black oxide finish, it meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding mechanical and structural assemblies. The 1/4-20 UNC thread is fully threaded along the 1-1/8 inch length under head, driven with a 3/16 inch hex key. Machinists, millwrights, and general maintenance tradespeople install this fastener in equipment, fixtures, and fabricated assemblies where a flush or recessed head is required.

This screw is used across a wide range of industrial and commercial applications including machinery guarding, equipment enclosures, tooling fixtures, and mechanical assemblies. The 1/4-20 UNC thread standard is one of the most common inch-series thread sizes, making this fastener appropriate for general-purpose bolted connections in light to medium mechanical assemblies. Its black oxide finish provides a degree of corrosion resistance suitable for indoor and protected environments.

Key Features

• Alloy steel construction meets ASTM A574 for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Fully threaded 1-1/8 inch length under head for maximum thread engagement
• 3/16 inch hex socket drive for use with standard hex keys or Allen drivers
• 1/4-20 UNC thread form conforms to ASME/ANSI B18.3
• Sold individually with a minimum order quantity of 100 pieces

Compatibility

Designed as an OEM-style and general-purpose replacement or stock fastener for any assembly requiring a 1/4-20 UNC hex socket cap screw with a 1-1/8 inch length under head per ASME/ANSI B18.3.

Installation Notes

Install using a 3/16 inch hex key or appropriately sized Allen driver. Ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from the equipment manufacturer or relevant ASME standards for 1/4-20 alloy steel fasteners. Do not exceed the rated torque for the fastener grade, as over-torquing can cause thread stripping or fastener failure.
