Acco Peerless Chain Chain - High Test 40/43

Acco Peerless Chain Grade 43 High Test Chain Solutions

Acco Peerless Chain's Grade 43 (G4) High Test chain features high tensile strength carbon steel with an ISO short link that provides greater strength-to-weight ratio than proof coil chain. As part of Acco Peerless Chain's comprehensive marine and industrial product line, their High Test 40/43 chain offerings represent decades of manufacturing excellence specifically engineered for demanding applications where reliability and performance are critical.

ACCO G43 Chain Design and Engineering

The ISO short link design makes the chain more flexible and ideally suited as a windlass chain, addressing a key concern for marine operators who need smooth operation through windlass systems. Grade 43 chain is about 35% stronger than conventional BBB chain, which allows you to save weight without sacrificing anchoring security. This engineering advantage makes Acco's High Test chain particularly valuable for applications where both strength and weight considerations matter.

The working load limit is approximately twice that of BBB or proof coil chain of comparable size, making it an efficient choice for load securement and general-purpose applications. Grade 43 High Test Chain features both high tensile strength and resistance to wear needed by modern hauling and heavy duty trucking, farm and construction firms, with working load limits that exceed those of ordinary low carbon or general utility chain.

Corrosion Protection and Durability

In the hot-dip process, this chain is specially shot-peened before galvanizing to create long-lasting protection against corrosion. Acco Peerless Chain applies an extra-thick hot-dip galvanized finish specifically recommended for marine applications, ensuring the chain withstands harsh saltwater environments. It comes with a two-year guarantee against rusting and is made in the U.S. out of high-carbon steel so it resists wear, making it suitable for abrasive anchoring situations and heavy-duty industrial use.

Manufacturing Heritage and Quality Standards

The acquisition of American Chain Company (ACCO) in July of 2006 expanded the industrial market for Peerless, specifically for Overhead Lifting and Marine products. Grade 43 replaces ACCO Grade 40 high-test designation with chain links now marked "G4", and ACCO chain is manufactured by Peerless Industrial Group. This consolidation brought together decades of chain manufacturing expertise and advanced production capabilities. Made in USA and comes in a self-colored or zinc finish, the chain meets ASTM and NACM specifications for quality assurance.

Application Versatility

While Acco's Grade 43 High Test chain excels as anchor and windlass chain for marine applications, its versatility extends across multiple industries. A general utility chain for farm, industrial and home applications such as: log chain, cargo lashing, pipeline hanging, tailgate, guard rail, tow and switch chain. The calibrated link dimensions ensure compatibility with most windlass wildcats carrying an "HT" designation, though compatibility verification with specific equipment manufacturers is always recommended before purchase.
