T-Bolts

Also known as tank-strap bolts, these T-bolts are commonly used with a band clamp or a strap to hold fuel tanks and other objects in place. The large T-shaped head provides a secure grip for steady tightening.

Steel—Steel T-bolts without a finish are ready to be painted or finished.

Black-Oxide Steel—Black-oxide steel T-bolts are mildly corrosion resistant in dry environments.

Zinc-Plated Steel—Zinc-plated steel T-bolts resist corrosion in wet environments.

Coarse Thread—Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch.

Fine Thread—Fine threads are closely spaced to prevent loosening from vibration.

Length—Length is measured from the top of the head.

Thread Spacing—Match the thread spacing of mating components.

T-Bolts with Collar

Also known as clamping pins, these bolts have a collar that slides along the shaft and can be welded in place to hold work and prevent over torquing. The large T-shaped head provides a secure grip for steady tightening. The black-oxide finish provides corrosion resistance in dry environments.

Length—Length is measured from the top of the head.
