Key features

• Thread size: 8-32
• Length: 3/8 inch

• Application: Ideal for wooden joints, furniture, cabinetry, and other light-duty assemblies

Why choose these carriage bolts? The combination of steel strength, black oxide finish, and oil treatment provides reliable performance with improved rust resistance in indoor environments. The square neck digs into the wood to hold the bolt in place as you tighten a nut on the opposite side.

Installation tips

• Drill a pilot hole sized to fit the bolt shank for a clean fit
• Insert the bolt through the top piece and align with a nut on the opposite side
• Use a wrench to secure the nut while the square neck prevents the bolt from turning
