Holo-krome 64016 Button Socket Cap Screw 8-32 1/4 in

Product Description

The HOLO-KROME 64016 is an 8-32 button socket cap screw designed for applications requiring a low-profile fastener with reliable clamping strength. Manufactured from alloy steel with a black oxide finish, this screw measures 1/4 inch in length under the head and is fully threaded to UNRC standards. The hex socket drive accepts a 3/32-inch hex key for installation and removal. Hardness is rated at 38 HRC, meeting ANSI/ASME B18.3 and ASTM F835 fastener standards. Licensed tradespeople and maintenance technicians working on equipment assemblies, panels, and mechanical enclosures will find this fastener suited to tight-clearance installations where a standard socket head cap screw profile is too tall.

This screw is appropriate for use in light-duty mechanical assemblies, electrical enclosures, HVAC equipment panels, and industrial equipment housings where a button head profile reduces interference with adjacent components. The 8-32 UNC thread and 3A thread fit class provide consistent engagement in tapped holes following standard inch-series threading. The black oxide finish offers mild corrosion resistance in dry indoor environments. Minimum order quantity is 100 pieces per order.

Key Features

• Button head profile keeps a low height of 0.087 inches for tight-clearance installations
• Alloy steel construction rated at 38 HRC hardness for reliable clamping performance
• Black oxide finish provides mild corrosion resistance in dry environments
• Hex socket drive sized at 3/32 inches for precise torque application with a standard hex key
• Fully threaded 8-32 UNC at 3A fit class per ANSI/ASME B18.3 and ASTM F835

Compatibility

Designed as an OEM-style replacement or direct-use fastener for standard 8-32 UNC tapped hole applications requiring a button head socket cap screw per ANSI/ASME B18.3.

Installation Notes

Installation requires a 3/32-inch hex key or ball-end driver. Power down or de-energize any equipment before accessing fastened panels or enclosures. Verify the receiving tapped hole meets 8-32 UNC thread specifications before installation. Do not exceed the design load capacity of the alloy steel construction in high-vibration or high-stress structural applications without engineering review.
