Steel Heavy Hex Head Screws
for High-Pressure Applications
These Grade B7 steel screws are nearly twice as strong as our stainless steel screws for high-pressure applications. Also known as pressure bolts, they meet the high-pressure and high-temperature regulations of ASTM A193 and are used to secure pressure tanks, valves, and flanges. Length is measured from under the head. Screws should be used with ASTM A194 nuts.
Partially threaded screws come with precise threaded and unthreaded portions, allowing you to place only the stronger unthreaded portion (grip) in joints subjected to sideways forces.

Rotating Eyebolts—For Lifting
Unlike conventional eyebolts, you can rotate the eye 360° to match the angle of your load.
Powder-coated steel eyebolts are impact resistant, but less corrosion resistant than stainless steel eyebolts. They include a removable key for tightening the bolt.
Note: Capacities listed are for vertical lifting only. Eyebolts with shoulder can be used for angular lifting up to 45°, but the capacities will be significantly reduced. For angular lifting, we recommend Hoist Rings.
Warning: Never use to lift people or items over people.
