Steel Hex Head Screws for Blind Holes
 |  |
Installed View |
Install these screws when you can only access one side of material. They're a higher-strength alternative to blind rivets. To install, hold the washer in place with a wrench, then use a hex socket to turn the screw. As the screw is tightened, the attached nut expands the sleeve to create a strong clamping force on the back of the material.
Head height does not include the washer. Length is measured from under the washer.
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.
