Tow Chain | McMaster-Carr

Bind, bundle, tow, and haul—this steel chain has hooks on each end for versatility. This chain is either Grade 43 or 70, so it’s strong enough to secure heavy loads but lighter in weight than higher-grade chain made for lifting. It meets D.O.T. regulations for use on roadways.

Warning: Never use for lifting applications. See Extra Heavy Duty Chain for Lifting.

Made in the U.S.

Chain that is made in the U.S. is forged and tempered for strength and durability.

Extra Heavy Duty Chain for Lifting

Lift, hoist, and rig heavy equipment, vehicles, containers, and more with the strongest chain we offer. This chain is graded by weight capacity, so you can pick the best option whether you're hauling a bulldozer or unloading cargo from a ship. Look for the manufacturer's stamp on each link to confirm the grade.

When using fittings with chain, match the trade size and meet or exceed the chain’s grade to avoid chain damage or failure.

Warning: Never use chain to lift people or items over people.

Grade 50 Chain—This chain combines corrosion resistance and strength for lifting in food processing and marine environments.

High-Temperature Grade 63 Chain—With a maximum temperature of 650° F, this chain withstands higher temperatures than other steel chain. It's ideal for lifting in steel mills, refineries, and other hot environments.

Grade 80 Chain—Your go-to option for most lifting jobs. Rig and lift industrial vehicles, heavy machinery, and shipping containers with this chain.

Grade 100 Chain—For exceptionally heavy lifting jobs. It's approximately 25% stronger than Grade 80 chain to handle larger loads and continuous lifting tasks in settings such as construction and mining.

Grade 120 Chain—The strongest chain in the industry at approximately 20% stronger than Grade 100 chain. The uniquely shaped links increase the chain's capacity and minimize wear, so you can use a smaller size than Grade 80 or 100 chain to lift the same amount of weight.

Steel—Best for dry environments since moisture will cause this chain to rust.

Black Painted Steel—Best for dry environments as paint may chip and corrode over time.

Zinc-Plated Steel—A common and economical choice, the zinc plating resists occasional moisture.

Black Zinc-Plated Steel—A common and economical choice, the zinc plating resists occasional moisture.

Powder-Coated Steel—Powder coating steel gives it a colored finish and a strong barrier against moisture and mild chemicals.

Highly Corrosion-Resistant 316 Stainless Steel—Our most corrosion-resistant chain holds up in any environment. It won't degrade even when exposed to salt water, acids, and harsh chemicals such as bleach.

Wear Gauges

Measure the maximum amount of wear allowed by OSHA on links of Grade 80 or 100 steel chain. If you can insert the gauge over any part of the link, you should take the chain out of service.

Heavy Duty Chain

Bind, tie down, and tow loads with this chain. This chain is graded based on weight capacity, so you'll always know exactly how much it can handle. Look for the manufacturer's stamp on each link to confirm the grade.

When using fittings with chain, match the trade size and meet or exceed the chain’s grade to avoid chain damage or failure.

Warning: Not for overhead lifting.

Grade 30 Chain—An economical choice for everyday industrial jobs that require only moderate strength. It's commonly used to create guardrails and to secure loads on farms and construction sites.

Tangle-Resistant Grade 30 Chain—The strongest tangle-resistant chain we offer. Shorter links make this chain easier to coil and less likely to knot when you're trying to store or transport it.

Grade 43 Chain—50% stronger than Grade 30 chain, this chain is great for towing as well as quickly securing and releasing large loads when logging.

High-Temperature Grade 63 Chain—This chain withstands temperatures up to 500° F, making it excellent for tie downs and towing in steel mills, refineries, and other hot environments.

Grade 70 Chain—Secure vehicles, machinery, and other loads on trailers and trucks for safe transportation. It's approximately 20% stronger than Grade 43 chain and 60% stronger than Grade 30 chain. Also known as transport chain, it meets D.O.T. standards for load securement.

Steel—Best for dry environments since moisture will cause this chain to rust.

Zinc-Plated Steel—A common and economical choice, the zinc plating resists occasional moisture.

Zinc-Yellow-Chromate-Plated Steel—Won't scratch or wear away as fast as clear zinc plating and resists occasional moisture. The distinctive golden color confirms this chain is compliant with Department of Transportation (DOT) regulations.

Galvanized Steel—A thick coating protects this chain in wet and outdoor environments about as well as 304 stainless steel, but it corrodes when exposed to salt water and chemicals.

Powder-Coated Steel—Powder coating steel gives it a colored finish and a strong barrier against moisture and mild chemicals.

Trailer Safety Chains

S-Hook

Latching Hook

Keep trailers attached to their vehicles even when the hitch fails. Use chains in pairs. The maximum trailer weight per pair must meet or exceed maximum trailer weight. Maximum trailer weight is the total weight being towed.

Warning: Never use for lifting applications. See Chain—For Lifting.
