About Hex Head Screws and Bolts
More
Tight-Spot Hex Head Screws
A high-strength alternative to blind rivets, use these screws when only one side of the material is accessible. To install, hold the washer in place with a wrench, and then use a hex socket to turn the screw. When the screw is tightened, the attached nut expands the sleeve to create a strong clamping force on the back of the material. Dimensions meet ISO 4017 (formerly DIN 933) specifications. Length is measured from under the head.

Hex Head Removable-Bolt Anchors for Block and Brick
A hex head allows for a secure grip with a wrench. Also known as sleeve anchors, these have a sleeve that expands for a secure hold in block and brick. They're often used to hold steel and wood panels, doors, framing, and shelving. To install, tap the anchor into a hole and tighten the bolt to expand the sleeve. As you tighten, the nylon ring compresses to secure the fixture against the base material. Made from 18-8 stainless steel, they're chemical resistant and may be mildly magnetic. Pull-out strength and shear strength values are 25% of the ultimate values.

Flat Head Removable-Bolt Anchors for Block and Brick
Bolts are beveled under the head for a flush finish in countersunk holes. Also known as sleeve anchors, these have a sleeve that expands for a secure hold in block and brick. They're often used to hold steel and wood panels, doors, framing, and shelving. To install, tap the anchor into a hole and tighten the bolt to expand the sleeve. As you tighten, the nylon ring compresses to secure the fixture against the base material. Made from zinc plated steel, they resist corrosion in wet environments. Pull-out strength and shear strength values are 25% of the ultimate values.

Removable-Bolt Anchors for Concrete
Turn the bolt to expand the nut for a secure hold in concrete. These anchors are often used to anchor machinery. Bolts can be removed and reused in the same hole or used in a new hole along with a replacement expander nut (sold separately). To install, thread the nut onto the tapered bolt and insert into a hole. Made from zinc-plated steel, they resist corrosion in wet environments. Pull-out strength and shear strength values are 25% of the ultimate values.
