Value Collection 015499BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 015499BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assembly, fabrication, and maintenance work. Threaded to 7/8-9 UNC with a 2-1/2 inch length under head and partial threading, this fastener is driven with a 3/4 inch hex key. The alloy steel construction delivers the tensile strength required for load-bearing joints, while the black oxide coating provides a baseline level of corrosion resistance and reduces light reflection in finished assemblies. Machinists, millwrights, and industrial maintenance technicians regularly specify this screw type where a flush or recessed drive profile is needed.

This screw fits applications requiring a heavy-duty socket cap fastener in the 7/8-9 UNC thread family. Common installation scenarios include structural clamping fixtures, machine bases, tooling plates, and equipment frames where high clamp loads are required. The partial threading allows the unthreaded shank to act as a locating feature in close-tolerance bores. Suitable for both light industrial and heavy industrial environments where alloy steel and black oxide finish meet the service requirements.

Key Features

• 7/8-9 UNC thread size for heavy-duty fastening applications
• 2-1/2 inch length under head with partial threading for shank-location capability
• Alloy steel construction for high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• 3/4 inch hex drive for use with standard hex keys or socket drivers
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard 7/8-9 UNC hex socket cap screw suitable for use in any application requiring a fastener conforming to ASME/ANSI B18.3, ASTM A574, or IFI 124 specifications.

Installation Notes

Installation is performed using a 3/4 inch hex key or socket driver; ensure the drive tool is fully seated before applying torque to avoid rounding the socket. De-energize and lock out any machinery before replacing or installing fasteners in mechanical assemblies per applicable safety procedures. Inspect mating threaded holes for damage or contamination before installation. Do not exceed the rated clamp load for the alloy steel grade and thread size in use.
