Value Collection 307174BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 307174BR is a fully threaded hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. Made from alloy steel with a black oxide finish, this fastener delivers reliable clamping force in demanding environments. It features a 3/4-10 UNC thread size, a 2-1/2 inch length under head, and a 9/16 inch hex drive. The black oxide coating provides mild corrosion resistance and reduces light reflection on exposed hardware. This screw meets ASTM A574 standards, making it suitable for high-strength socket cap screw applications where dimensional and mechanical consistency is required.

This fastener is used in a wide range of maintenance, repair, and manufacturing settings. Common applications include machinery assembly, fixture building, equipment mounting, and general metalworking. The 3/4-10 UNC coarse thread is a standard choice for steel-to-steel fastening where quick assembly and reliable thread engagement are priorities. Millwrights, machinists, maintenance technicians, and industrial assembly workers regularly specify this size for structural and mechanical connections.

Key Features

• 3/4-10 UNC coarse thread for strong, reliable thread engagement in steel applications
• 2-1/2 inch length under head with full threading along the entire shank
• 9/16 inch hex socket drive for use with standard hex keys and socket drivers
• Alloy steel construction meets ASTM A574 high-strength socket cap screw standard
• Black oxide finish provides mild corrosion resistance and a low-reflectance appearance

Compatibility

Designed as an OEM-style replacement or direct-use fastener for applications requiring a 3/4-10 UNC fully threaded hex socket cap screw conforming to ASTM A574.

Installation Notes

Installation should be performed by qualified machinists, millwrights, or maintenance technicians familiar with high-strength fastener procedures. Always verify thread engagement depth and mating material suitability before driving. Use the correct 9/16 inch hex key or driver to avoid rounding the socket. Apply thread lubricant or threadlocker as required by the specific assembly specification.
