About Hex Head Screws and Bolts

Choose a hex head fastener with the right threading, thread size, material, and strength for your equipment.

Steel Hex Head Screw Kits


	Fully Threaded	Partially Threaded

Everything you need for a complete, strong joint—the screws in these kits come with compatible nuts and washers. The screws have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive. Washers distribute pressure on both sides of your material, so the nut tightens onto the screw without damaging surfaces.

Screw length is measured from under the head.

Medium-Strength Fastener—Your go-to screws for fastening most machinery and equipment. They have tensile strengths from 90,000 to 120,000 psi.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

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 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.

Medium-Strength Fastener—Your go-to screws for fastening most machinery and equipment. They have tensile strengths from 90,000 to 120,000 psi.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

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.

Medium-Strength Fastener—Your go-to screws for fastening most machinery and equipment. They have tensile strengths from 90,000 to 120,000 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.

Steel Serrated-Flange Hex Head Screw and Nut Assortments

Stock up on fasteners in various sizes to create vibration-resistant joints. The screws and nuts in these assortments both have a flange with a serrated edge that grips your material to keep screws in place. 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.

Medium-Strength Fastener—Your go-to screws for fastening most machinery and equipment. They have tensile strengths from 90,000 to 120,000 psi.

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.
