Holo-krome 64024 Button Socket Cap Screw 8-32 3/4 in

Product Description

The HOLO-KROME 64024 is a button socket cap screw designed for applications requiring a low-profile head with a secure hex socket drive. Sized at 8-32 thread with a 3/4-inch length under head, this fastener is fully threaded and manufactured from alloy steel with a black oxide finish. It meets ANSI/ASME B18.3 and ASTM F835 standards and carries a 3A thread fit class per UNC right-hand thread specification. Hardness is rated at 38 HRC, making it suited for moderate- to high-strength fastening tasks in mechanical and industrial assemblies.

This button socket cap screw is used where a smooth, rounded head profile is needed in tight clearance areas or where a standard hex head would interfere with adjacent components. Common applications include equipment enclosures, panel assemblies, brackets, and light-duty structural connections in HVAC equipment, electrical enclosures, and general mechanical assemblies. The hex socket drive accepts a 3/32-inch hex key for installation. This item is sold individually but is subject to a minimum order quantity of 100 pieces per order.

Key Features

• Button head profile provides low clearance and a smooth appearance in finished assemblies
• 3/32-inch hex socket drive for precise torque application with standard hex keys
• Alloy steel construction with 38 HRC hardness for dependable strength in mechanical service
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Fully threaded 8-32 UNC right-hand thread with 3A fit class for consistent engagement
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or service fastener for assemblies requiring an 8-32 UNC button socket cap screw with a 3/4-inch length under head and 3/32-inch hex socket drive.

Installation Notes

Installation is performed with a 3/32-inch hex key or Allen driver. De-energize and lock out all equipment before replacing fasteners on live assemblies. Follow applicable ANSI torque guidelines for 8-32 alloy steel fasteners and inspect threads for damage before installation. Do not exceed the rated hardness load for the screw size and material grade.
