The VALUE COLLECTION BD909 is a Grade 2 steel hex head cap screw with a black oxide finish, sold in a package of 25. It features a 5/16-24 thread size and a 3/4-inch length under the head. The black oxide coating provides moderate corrosion resistance and reduces light reflection, making it suitable for general-purpose mechanical and structural fastening applications. This screw is installed using a standard hex wrench or socket and is well suited for maintenance, repair, and fabrication work across HVAC, plumbing, electrical, and general trade environments.
These hex head cap screws are used in a wide range of light-duty fastening applications where a unified fine-thread profile is required. The 5/16-24 UNF thread is commonly found in machine assemblies, equipment panels, and component brackets. The package quantity of 25 makes this SKU appropriate for both single-job use and small-quantity stocking. Tradespeople and general contractors will find this fastener suitable for indoor and sheltered-outdoor installations where moderate environmental exposure is expected.
Designed as a general-purpose hex head cap screw for use in mechanical assemblies, equipment enclosures, and structural components requiring a 5/16-24 UNF thread pattern.
Installation requires a standard hex socket or open-end wrench sized to the 1/2-inch hex head. Ensure the mating thread is clean and free of debris before installation. Power down or de-energize any equipment before fastening components near electrical assemblies. Follow applicable torque guidance from the equipment manufacturer for the specific assembly being serviced.
