Holo-krome 64082 Button Socket Cap Screw 1/2-13 2in

Product Description

The HOLO-KROME 64082 is a button socket cap screw designed for applications requiring a low-profile head with high tensile strength. Sized at 1/2-13 thread with a 2-inch length under head, this fastener is fully threaded and manufactured from alloy steel with a black oxide finish. The hex socket drive accepts a 5/16-inch key for installation and removal. Hardness is rated at 38 HRC, making it suitable for demanding mechanical assemblies where a flush or near-flush head profile is required. Licensed trades and mechanical contractors rely on this type of fastener in structural, machine, and equipment assembly work.

This button socket cap screw is used in general industrial, mechanical, and equipment fabrication applications where a domed, low-profile head is preferred over a standard cap or flat-head style. The 1/2-13 UNC thread conforms to ANSI/ASME B18.3 and ASTM F835 standards. It is suited for both light and heavy mechanical assemblies where controlled clamping force and thread engagement are critical. Minimum order quantity is 25 pieces per order.

Key Features

• Button head profile provides low clearance and broad bearing surface
• Alloy steel construction rated at 38 HRC for high strength applications
• Black oxide finish adds mild corrosion resistance and reduces light reflection
• 5/16-inch hex socket drive for precise torque application
• Fully threaded 1/2-13 UNC right-hand thread, Class 3A fit
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 1/2-13 UNC button socket cap screw suitable for use in any application conforming to ANSI/ASME B18.3 specifications for hex socket button head cap screws.

Installation Notes

Installation requires a 5/16-inch hex key or socket driver. Always de-energize and lock out equipment before fastener installation or removal on powered machinery. Apply torque gradually and evenly; refer to applicable ANSI or equipment manufacturer torque tables for the correct value for this thread size and material class. Do not substitute a smaller drive key, as this can damage the socket recess and prevent proper torque transfer.
