T-Slot Bolts

For quicker setups than a separate T-slot nut and stud, slide these bolts into T-slot tracks on machine tool tables.

Machined Neck

Flat surfaces on the neck fit securely in the T-slot so the bolt doesn't wobble.

Black-Oxide Steel—Our strongest T-slot bolts. The dark, matte coating withstands occasional moisture.

DIN 787—Bolts meet DIN dimensional and material requirements. Slide them into DIN 650 T-slots.

Drop-In T-Slot Bolts

Install these bolts at any point along a T-slot track. They drop in from the top, so you don’t have to slide them down the track’s length. These bolts are especially useful when you need to add clamping points to an existing fixture. They’re more versatile than other T-slot bolts that only install at the end of a track. But because drop-in bolts make less contact, they have lower load capacities.

Machined Neck


Top View

Flat surfaces on the neck fit securely in the T-slot so the bolt doesn't wobble.
