Value Collection 015497BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 015497BR is a hex socket cap screw designed for high-strength fastening applications where a recessed drive is required. Sized at 7/8-9 UNC with a 2-1/4 inch length under head and a 3/4 inch hex drive, this fastener is fully threaded along its entire shank. The alloy steel construction with a black oxide finish provides corrosion resistance and reduces light reflection in industrial environments. This screw is manufactured to ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it a code-compliant choice for mechanical assemblies requiring a traceable fastener specification. Machinists, millwrights, and industrial maintenance technicians typically install this type of fastener.

This hex socket cap screw is suited for heavy-duty mechanical assemblies, machinery frames, fixtures, and structural components where a flush or low-profile head is needed. The fully threaded shank allows maximum thread engagement across the full grip length, which is particularly useful in blind-hole applications and where clamp load distribution is critical. It is commonly used in manufacturing, fabrication shops, and industrial maintenance settings where alloy steel fasteners with standardized dimensions are specified.

Key Features

• 7/8-9 UNC thread size for use in standard inch-series tapped holes
• 2-1/4 inch length under head with full threading along the entire shank
• 3/4 inch hex drive socket for use with standard hex keys or socket drivers
• Alloy steel construction meets ASTM A574 high-strength cap screw requirements
• Black oxide finish provides mild corrosion resistance and reduced surface reflectivity
• Manufactured to ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard 7/8-9 UNC hex socket cap screw for use in any inch-series tapped hole conforming to ASME/ANSI B18.3 dimensional requirements.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a properly rated 3/4 inch hex key or socket driver. Verify that the mating tapped hole is clean, undamaged, and cut to 7/8-9 UNC specification before installation. Apply thread lubricant or thread-locking compound as required by the assembly specification. Never exceed the torque values specified in the applicable engineering documentation for this fastener size and grade.
