When a worn or broken roller chain link brings your conveyor, drive system, or machinery to a halt, every minute of downtime costs you. Whether you're a maintenance technician, a farm equipment operator, or a DIY builder, you need A2 stainless steel roller chain connecting links that install quickly and hold under load — without corroding in wet or outdoor environments.
These A2 stainless steel roller chain connecting links are available in both full-link and half-link configurations, covering sizes from 1/4" (04C) through 1-1/4" (20A) and metric equivalents including 06C, 08A, 10B, 12B, and 16B. Each link is precision-formed from A2 (304) stainless steel, delivering a corrosion-resistant, food-grade-compatible connection point. Sold individually or in multi-packs of 2, 5, or 10 pieces.
Typical applications include agricultural roller chain repair, industrial conveyor chain maintenance, bicycle and go-kart drive chain assembly, and light-duty power transmission systems where stainless steel roller chain connecting links are required for moisture-exposed or washdown environments.
Formed from A2 stainless steel for reliable corrosion resistance in wet, outdoor, and light washdown environments — suitable for food-adjacent and agricultural applications.
Spring clip (cotter pin) retention allows tool-free installation and removal, reducing chain repair time significantly compared to riveted master links.
Full connecting links restore a broken chain to its original length; half links let you adjust chain length by exactly one half-pitch — essential when an odd number of links is needed.
Available from 1/4" (04C) to 1-1/4" (20A) in imperial, plus metric sizes 06C, 08A, 10B, 12B, and 16B — covering the most common ANSI and ISO roller chain standards.
Manufactured to standard roller chain pitch and roller dimensions, ensuring drop-in compatibility with matching chain strands without modification.
Order 1, 2, 5, or 10 pieces per size — ideal for single repairs, stocking a maintenance kit, or equipping a workshop with spare connecting links across multiple chain sizes.

A full connecting link replaces a standard master link and keeps your chain at its original length. A half link is one half-pitch shorter and is used when your chain requires an odd number of pitches to reach the correct tension — common when shortening a chain by a single link leaves it too long. Check your chain's current link count and sprocket center distance before deciding.
Match the connecting link size to your chain's pitch designation. For example, a #40 ANSI chain (1/2" pitch) uses a 1/2" (08B) connecting link. If you're working with ISO metric chain, match the metric designation (e.g., 10B, 12B). When in doubt, measure the pitch — the center-to-center distance between two adjacent pins — and compare to the size options listed in the variant selector.
A2 (304) stainless steel offers good tensile strength suitable for light-to-medium duty roller chain applications including agricultural equipment, conveyors, and general power transmission. It is not recommended for high-shock or heavy-duty industrial drives where carbon steel or A4 (316) stainless links would be more appropriate. Refer to the working load limit for your specific size variant before use.
A2 stainless steel provides solid corrosion resistance against rain, humidity, and mild chemical exposure, making it well-suited for outdoor machinery, irrigation equipment, and food-processing-adjacent applications. For highly aggressive environments — such as saltwater or strong acid/alkali exposure — consider A4 (316) stainless steel instead.
No special tools are required. The fast-post (spring clip) design allows you to slide the outer plate onto the pins and snap the clip into the grooves by hand or with a small flathead screwdriver. Always ensure the open end of the spring clip faces away from the direction of chain travel to prevent accidental disengagement.
These links are manufactured to standard ANSI/ISO roller chain dimensions and are compatible with most standard-pitch roller chains of the matching size. However, compatibility can vary with non-standard or specialty chains (e.g., double-pitch, hollow-pin, or extended-pin chains). Always verify the pitch, roller diameter, and inner plate width of your existing chain before ordering.
For a single repair, the 1 Pcs option is the most economical choice. If you maintain multiple machines or want to keep spares on hand, the 5 Pcs or 10 Pcs packs offer a lower per-unit cost and reduce the risk of downtime when a link fails unexpectedly. Maintenance workshops typically stock multi-packs across the most common sizes they service.
