Value Collection 201141P Button Socket Cap Screw 5/16-18x1

Product Description

The VALUE COLLECTION 201141P is a button socket cap screw designed for applications requiring a low-profile fastener with a strong hex socket drive. Sized at 5/16-18 with a 1-inch length under the head, this screw is fully threaded and machined from alloy steel with a black oxide finish for corrosion resistance in dry or mildly humid environments. It meets ANSI/ASME B18.3 and ASTM F835 standards, ensuring dimensional accuracy and mechanical reliability. With a hardness rating of 36-43 HRC, it delivers solid clamp load in medium-duty fastening assemblies. Machinists, millwrights, and general contractors install this type of fastener across a wide range of structural and mechanical applications.

This button socket cap screw is suited for use in manufacturing, fabrication, and mechanical assembly where a rounded button head is needed to reduce snag points or clear tight clearances. The 3/16-inch hex socket drive accepts standard hex keys and T-handle drivers. The UNC thread form and Class 3A thread fit make it compatible with standard tapped holes in steel, aluminum, and other common substrate materials. It is sold individually but must be ordered in multiples of 100 units per the minimum order requirement.

Key Features

• Button head profile reduces protrusion and eliminates sharp edges in assembled components
• Alloy steel construction with 36-43 HRC hardness for medium-to-high-strength fastening
• Black oxide coating provides mild corrosion resistance and reduces light reflection
• 3/16-inch hex socket drive compatible with standard hex keys and socket bits
• Fully threaded 5/16-18 UNC Class 3A thread fit for precise engagement in tapped holes
• Meets ANSI/ASME B18.3 and ASTM F835 standards for dimensional and mechanical compliance

Compatibility

Designed as a standard UNC replacement or new-installation fastener for tapped 5/16-18 holes in steel, aluminum, and other common materials used in mechanical and fabrication assemblies.

Installation Notes

Install using a 3/16-inch hex key or socket bit rated for the torque requirements of the application. Verify the receiving hole is tapped to 5/16-18 UNC and is free of debris before driving the screw. Do not exceed the designed torque range for the alloy steel grade to avoid thread stripping or fastener failure. Follow applicable industry standards and facility safety protocols when working with power tools or presses during installation.
