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.

Steel Flanged Hex Head Screw and Nut Assortments

A range of flanged fasteners for a variety of jobs. The screws and nuts in these assortments both have a flange that spreads pressure over a wide area to protect thin and soft materials. The screws have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive.

Head height includes the flange. Length is measured from under the flange.

High-Strength Fastener—Commonly used to fasten components in valves, pumps, motors, and other high-stress applications. These screws have a tensile strength of 125,000 to 160,000 psi.

Steel Hex Head Screw, Nut, and Washer Assortments

Keep a range of hex head screw, nut, and washer sizes on hand for a variety of jobs. The screws in these assortments have heads with six flat sides to keep wrenches and sockets slipping and rounding off the drive.

Length is measured from under the head.

High-Strength Fastener—Commonly used to fasten components in valves, pumps, motors, and other high-stress applications. These screws have a tensile strength of 125,000 to 160,000 psi.

Zinc-Yellow-Chromate-Plated Steel—With slightly better corrosion resistance than zinc-plated steel screws, these stand up to more frequent exposure to moisture.
