Product Sku: HW-K16-BHCS-108
Replacement button head cap screws — a bag of 16, 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, so you can replace a lost fastener or expand your build with confidence.
- Quantity: 16 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)

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: bed rack assembly, MOLLE panel mounting, accessory and bracket installs, and any 5/16-18 T-slot or threaded application that needs a strong, clean-looking fastener.
