Holo-krome 61044 Flat Socket Cap Screw 3/8-24 X 1 in

Product Description

The HOLO-KROME 61044 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener with high tensile strength. The 82-degree flat head seats flush with the mating surface when installed in the correct countersink. Drive is a 7/32-inch hex socket, requiring an Allen-style driver or hex key. Manufactured from alloy steel with a black oxide finish, the 61044 carries a hardness rating of 39-44 HRC, making it suitable for demanding mechanical assemblies where standard steel fasteners are insufficient. Thread fit is Class 3A, indicating a close tolerance for precision applications.

This screw is intended for use in mechanical, industrial, and light structural assemblies where a low-profile countersunk head is required. The 3/8-24 UNF thread is a fine-pitch designation, suited for applications requiring finer thread engagement than UNC equivalents, such as precision machinery components, tooling fixtures, or assemblies subject to vibration. The fully threaded, 1-inch overall length allows engagement across the full body of the fastener. This product is sold and ordered in multiples of 100 and packaged individually per unit count.

Key Features

• 82-degree flat head for flush countersunk installation
• 7/32-inch hex socket drive for positive torque transfer
• Alloy steel construction with 39-44 HRC hardness for high-strength applications
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Fully threaded along the entire 1-inch length
• Class 3A thread fit for close-tolerance precision assemblies
• Meets ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-use flat socket cap screw for any assembly specifying a 3/8-24 UNF x 1-inch overall length flat-head socket screw conforming to ASME B18.3 or ASTM F835.

Installation Notes

Installation requires a correctly sized 82-degree countersink in the mating material to achieve a flush seating surface. Use the correct 7/32-inch hex key or driver; undersized drivers will strip the socket. De-energize and lock out any machinery before fastener installation or removal per applicable safety procedures. Do not substitute this fine-thread UNF fastener in applications calling for UNC thread specifications.
