Value Collection 0250-126- Button Cap Screw 5/16-18 2in 50pk

Product Description

The VALUE COLLECTION 0250-126- is a fully threaded button socket cap screw designed for fastening applications requiring a low-profile head and high-strength alloy steel construction. The hex socket drive accepts a 3/16-inch hex key for installation and removal. Finished in black oxide for moderate corrosion resistance, this screw carries a thread size of 5/16-18 UNC and a length under head of 2 inches. It is sold in a package of 50 pieces. Hardness is rated at 36-43 HRC, making it suitable for structural and mechanical assemblies where clamp load and fatigue resistance matter.

This fastener is appropriate for use in general industrial, mechanical, and fabrication applications where a button head profile is required to minimize interference with adjacent components. The UNC thread form is standard in North American trade and manufacturing environments. Licensed tradespeople in HVAC, plumbing, electrical, and mechanical fabrication install these fasteners in equipment enclosures, brackets, panels, and light structural assemblies. The fully threaded shank ensures full thread engagement across the entire grip length.

Key Features

• Button head style provides a low-profile, rounded appearance with wide bearing surface
• 3/16-inch hex socket drive for standard allen key or hex bit installation
• Alloy steel construction rated 36-43 HRC for high strength and fatigue resistance
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Fully threaded shank maximizes thread engagement in thinner materials
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or general-use fastener for applications requiring a 5/16-18 UNC button socket cap screw with a 2-inch length under head in alloy steel construction.

Installation Notes

Installation requires a 3/16-inch hex key or hex socket bit. Power down or de-energize any equipment before accessing fastener locations on live systems. Apply thread-locking compound if vibration is a concern in the application. Follow applicable mechanical codes and equipment manufacturer torque guidelines when installing into tapped holes.
