BAG OF 32 EA - BHCS 5/16-18 X 5/8" GRADE 8/10.9 BLACK ZINC
Product Sku: HW-K32-BHCS-108
Replacement button head cap screws — a bulk bag of 32, sized 5/16"-18 x 5/8". These high-strength Grade 8 / 10.9 black zinc bolts are the same hardware we ship with our XTR bed racks and MOLLE accessories. The 32-count bag is the value pick for full builds, multi-panel MOLLE setups, or keeping spares on hand.
- Quantity: 32 screws per bag
- Type: Button Head Cap Screw (BHCS), socket / hex drive
- Thread: 5/16"-18 (coarse)
- Length: 5/8"
- Grade: Grade 8 / 10.9 (high tensile strength)
- Finish: Black zinc — corrosion-resistant and matte black to match your rack
The low-profile button head sits flush and clean against T-slot extrusion, MOLLE panels, and bracket hardware. Pairs with our 5/16-18 drop-in T-nuts for fast, no-weld mounting anywhere along the rack.
Common uses: full bed rack assembly, multi-panel MOLLE mounting, accessory and bracket installs, and any 5/16-18 T-slot or threaded application that needs a strong, clean-looking fastener.
