Value Collection 88547278 Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 88547278 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and construction assemblies. Sized at 1-8 UNC thread with a 3-inch length under head, this screw accepts a 3/4-inch hex drive for reliable torque transfer. The alloy steel construction delivers the tensile strength required for demanding load-bearing connections, while the black oxide coating provides a degree of corrosion resistance and reduces light reflection in finished assemblies. Fully threaded along its length, this fastener is suited for through-bolt applications and joints where maximum thread engagement is needed. Machinists, millwrights, and maintenance technicians commonly install this type of hardware.

This hex socket cap screw is appropriate for a wide range of general industrial and mechanical applications including machine frames, jigs, fixtures, and structural brackets. The 1-8 UNC coarse thread pitch is well suited for use in steel and iron components where fast assembly and strong clamping force are priorities. The black oxide finish makes it common in tooling and equipment where a low-profile, non-reflective appearance is preferred. It is installed using a 3/4-inch hex key or Allen-drive socket tool and is sold as a single-piece unit.

Key Features

• 1-8 UNC coarse thread for strong clamping force in steel and iron applications
• Fully threaded shank maximizes thread engagement for through-bolt use
• Alloy steel construction provides high tensile strength for load-bearing joints
• Black oxide coating adds corrosion resistance and a non-reflective finish
• 3/4-inch hex socket drive for positive torque transfer with standard Allen tools
• Single-piece packaging suits replacement and maintenance work

Compatibility

Designed as a standard 1-8 UNC hex socket cap screw for use in industrial machinery, structural assemblies, and mechanical fixtures requiring alloy steel fasteners with a hex socket drive.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians. Power down and de-energize any equipment before disassembling or replacing fasteners in mechanical assemblies. Use a correctly sized 3/4-inch hex key or drive socket to avoid rounding the socket head. Follow applicable torque specifications for the joint material and bolt grade as outlined in engineering drawings or fastener manufacturer guidelines.
