Holo-krome 64036 Button Socket Cap Screw 10-24 7/8in

Product Description

The HOLO-KROME 64036 is a button socket cap screw engineered for applications requiring a low-profile head and high clamping strength. It features a hex socket drive accepting a 1/8-inch hex key, a fully threaded alloy steel shank with 10-24 UNC threading, and a black oxide finish for moderate corrosion resistance. The thread fit is Class 3A for precise, consistent engagement. Hardness is rated at 38 HRC, making this fastener suitable for demanding mechanical assemblies. It is installed by machinists, millwrights, maintenance technicians, and mechanical contractors where a flush or recessed head profile is required and a standard hex bolt would interfere with adjacent components.

This screw is used in machine frames, fixture plates, panel assemblies, and equipment enclosures where a smooth, rounded head is preferable to a flat or countersunk profile. The 7/8-inch length under head suits light to medium material stack-ups in both ferrous and non-ferrous applications. The right-hand thread direction is standard for general mechanical assembly. This fastener ships in multiples of 50 per the minimum order requirement and is packaged individually by the lot.

Key Features

• Button head profile keeps fastener head low and smooth, reducing snag points in assemblies
• 1/8-inch hex socket drive for precise torque application with a standard hex key or T-handle driver
• Fully threaded 10-24 UNC shank, Class 3A thread fit for consistent engagement
• Alloy steel construction rated at 38 HRC hardness
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard replacement or new-installation button socket cap screw for any application specifying a 10-24 UNC, 7/8-inch length under head, button head, alloy steel fastener per ANSI/ASME B18.3 or ASTM F835.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel using a calibrated hex key or socket driver sized at 1/8 inch. De-energize all equipment and relieve any relevant pressure or load before replacing fasteners in live assemblies. Do not exceed the rated hardness class when substituting fasteners in torque-critical joints. Follow applicable ANSI or OEM torque guidelines for Class 3A 10-24 threaded joints.
