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.

Medium-Strength Steel Threaded Rods—Grade B7
Grade B7, these threaded rods have a tensile strength about one and a half times stronger than low-strength steel rods. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

High-Strength 410 Stainless Steel Threaded Rods—Grade B6
Stronger and more wear resistant than 18-8 stainless steel, these 410 stainless steel threaded rods are mildly chemical resistant. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges. All are magnetic.

Hoist Rings—For Lifting
Designed for angular lifting, hoist rings resist stresses that would bend or break an eyebolt. They have a lifting ring that pivots 180° front to back and a base that swivels 360° to compensate for pitch, roll, and sway when lifting heavy or unbalanced loads. Install the base of the hoist ring flush to the mounting surface and tighten to the recommended torque that is stamped on the ring. Torque wrenches are sold separately.
Machined hoist rings have a smooth finish to protect slings and hooks from damage and excess wear during lifting.
Black-oxide steel hoist rings have mild corrosion resistance.
Hoist rings that are CE marked meet European safety standards.
Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the hoist ring can lift is significantly reduced. For example, when lifting a 1,000 lb. load at a 45° angle, you must choose a hoist ring with a capacity of at least 1,400 lbs. Do not use at an angle less than 30°.
Warning: Never use to lift people or items over people.

Tension-Indicating Hoist Rings—For Lifting
An indicator dot changes from red to black when these hoist rings are properly tightened, eliminating the need for a torque wrench. The dot changes back to red if the hoist ring comes loose. Ideal for angular lifting, these hoist rings withstand stresses that bend or break eyebolts. They have a lifting ring that pivots 180° front to back and a base that swivels 360° to compensate for pitch, roll, and sway when lifting heavy or unbalanced loads. A black oxide finish gives these hoist rings mild corrosion resistance.
Install the base of these hoist rings flush to your mounting surface.
Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the hoist ring can lift is significantly reduced. For example, when lifting a 1,000 lb. load at a 45° angle, you must choose a hoist ring with a capacity of at least 1,400 lbs. Do not use at an angle less than 30°.
