18-8 Stainless Steel Hex Head Screws
Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Length is measured from under the head.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Screws that meet ASME, or ISO (formerly DIN), or DIN specifications comply with these dimensional standards.

Alloy Steel Socket Head Screws
With a tensile strength of 170,000 psi, these alloy steel screws are stronger than Grade 8 steel screws. Length is measured from under the head.
Black-oxide steel screws are mildly corrosion resistant in dry environments.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch.
Screws that meet ASTM A574, ASTM A574M, and ISO 898-1 comply with specifications and testing requirements for material quality.

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 Steel Threaded Rods
Comparable to Grade 8 steel, these threaded rods have a tensile strength of 150,000 psi, making them about 25% stronger than medium-strength steel rods.

Low-Strength Steel Threaded Rods
About half the strength of medium-strength steel threaded rods, use these for light duty hanging, mounting, and fastening.
Zinc-plated steel threaded rods are corrosion resistant in wet environments.

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.
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.
