Value Collection 015481BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 015481BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. Sized at 3/4-10 UNC with a 4-1/2-inch length under the head, this fastener is driven by a 5/8-inch hex key. It is constructed from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection on exposed hardware. This fastener meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it suitable for demanding torque and tensile load requirements. Machinists, millwrights, and maintenance technicians are the primary installers.

This cap screw is used in a wide range of applications including machine tool assemblies, jigs and fixtures, die sets, and general industrial fabrication. The 3/4-10 UNC coarse thread engagement provides strong pull-out resistance in steel and other ferrous base materials. Partial threading allows the unthreaded shank to act as a precision locating element in close-tolerance bores. It is appropriate for both light-manufacturing and heavy-industrial settings where a recessed hex drive is required to maintain a low-profile fastener head.

Key Features

• 3/4-10 UNC coarse thread for strong fastening in ferrous materials
• 4-1/2-inch length under head with partial threading for shank-guided alignment
• 5/8-inch hex socket drive for high-torque installation with a standard hex key or socket tool
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion resistance and a non-reflective surface
• Meets ASME/ANSI B18.3 and IFI 124 dimensional and performance standards

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for industrial assemblies requiring a 3/4-10 UNC partially threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a calibrated torque wrench and the appropriate 5/8-inch hex key or socket bit. De-energize and lock out all equipment before disassembly or fastener replacement in accordance with applicable OSHA lockout/tagout procedures. Inspect the mating threaded hole for damage or contamination before installation, and apply thread lubricant as appropriate for the load and environment. Do not substitute a smaller drive tool, as rounding the socket will render the fastener unserviceable.
