Value Collection 402292BR Hex Head Cap Screw 7/8-9 X 4 in

Product Description

The VALUE COLLECTION 402292BR is a 7/8-9 UNC hex head cap screw with a 4-inch length under head, manufactured from Grade 2 steel with a bright uncoated finish. The partial threading configuration is standard for this bolt length, providing a smooth shank section that resists shear loads in structural and mechanical assemblies. At 0.05 pounds per piece, this fastener suits general-purpose industrial, HVAC equipment mounting, and mechanical assembly applications where Grade 2 steel meets the required load specification. Installed with a standard hex wrench or socket, it covers a wide range of trade and light industrial fastening tasks.

This cap screw is suited for use in general construction, equipment framing, ductwork support structures, and mechanical assemblies where a 7/8-9 UNC coarse-thread fastener is called out. The bright uncoated finish is appropriate for indoor or dry-environment installations. Tradespeople in HVAC, plumbing, and light structural work commonly stock this size for equipment bases, vibration-isolation frames, and structural steel connections that do not require a corrosion-resistant coating.

Key Features

• 7/8-9 UNC coarse-thread specification for broad tooling and hardware compatibility
• 4-inch length under head with partial threading for shear-load applications
• Grade 2 steel construction for general-purpose mechanical fastening
• Bright uncoated finish suitable for dry or indoor service environments
• Inch measurement system — compatible with standard SAE tooling and hardware

Compatibility

Designed as a general-purpose UNC coarse-thread hex head cap screw for use wherever a 7/8-9 x 4-inch Grade 2 steel fastener is specified in mechanical or structural assemblies.

Installation Notes

Installation requires a standard hex socket or open-end wrench sized for a 7/8-9 fastener. Ensure mating threads are clean and free of debris before installation. Apply appropriate torque per the assembly specification for Grade 2 steel fasteners — do not substitute a higher-grade torque spec, as Grade 2 has lower yield strength than Grade 5 or Grade 8. No coating means bare steel is exposed, so apply thread lubricant or anti-seize in environments with moisture exposure to prevent galling.
