Holo-krome 60106 Flat Socket Cap Screw 3/8-16 X 1-3/4 in

Product Description

The HOLO-KROME 60106 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener with high tensile strength. Sized at 3/8-16 x 1-3/4 inches overall length, it features an 82-degree flat head geometry and a 7/32-inch hex socket drive. The fastener is fully threaded, conforming to UNC thread standard with a 3A thread fit class. Manufactured from alloy steel with a black oxide finish, it carries a hardness rating of 39-44 HRC. Licensed contractors, millwrights, and maintenance professionals typically install this hardware in mechanical assemblies where a low-profile head is required.

This screw is suited for industrial machinery, tooling fixtures, structural assemblies, and OEM equipment requiring countersunk fasteners. The 3/8-16 UNC thread size and 1-3/4-inch length make it a common choice in moderate-load mechanical connections. It meets ASME B18.3 and ASTM F835 standards, making it appropriate for use in precision assemblies where dimensional and mechanical compliance is required. A minimum order quantity of 50 pieces applies per order.

Key Features

• 82-degree flat head profile for flush countersunk installations
• 7/32-inch hex socket drive for standard Allen key or hex bit drivers
• Fully threaded along the 1-3/4-inch body length
• Alloy steel construction with 39-44 HRC hardness for high-load applications
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Meets ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style and general-use flat socket cap screw for 3/8-16 UNC countersunk fastener applications in industrial, mechanical, and structural assemblies.

Installation Notes

Installation requires a 7/32-inch hex key or matching hex socket bit driver. Countersink the mating hole to an 82-degree included angle prior to assembly to ensure proper head seating and flush fitment. Torque to specification for the fastener grade and application per applicable engineering standards. Follow all applicable safety procedures when working with high-strength fasteners in structural or load-bearing assemblies.
