Description
Overview:
This lynch pin is a sturdy, reusable fastener for securing moving or removable parts on agricultural, landscaping, and industrial machinery. The pin diameter is 7/16 in (approximately 11.1 mm), paired with a 42 mm inside-diameter spring ring for quick, tool-free locking. Made from steel with a corrosion‐resistant plated finish, it resists wear and the elements when used outdoors. The sprung ring snaps positively into place to stop vibration from shaking components loose, helping keep linkages, drawbars, tow points, and attachments secure in use. It suits a wide range of equipment such as compact tractors, mowers, trailers, cultivators, and loaders, where a reliable, quick-release retaining solution is needed. Supplied individually (each), it is practical for field repairs, workshop spares, and general maintenance kits.
Key Features:
- Pin diameter: 7/16 in (≈11.1 mm) for common implement and linkage sizes
- 42 mm inside-diameter ring gives good leverage for easy fitting and removal
- Ring thickness: 3.5 mm for dependable spring action and retention
- Positive spring-lock mechanism resists vibration and accidental release
- Steel construction with plated finish for durability and corrosion resistance
- Quick, tool-free operation saves time during attachment changes
- Smooth action ring is easy to grip with gloves in workshop or field conditions
- Versatile, reusable fastener supplied individually for maintenance and spares
Typical Applications:
Securing tractor linkages and top links, drawbars and clevises, trailer and implement hitches, mower decks, spreaders, loaders, and general plant equipment. Ideal wherever a removable pin needs a reliable retaining lock, especially in farming, groundskeeping, construction sites, and workshops where frequent attachment changes and vibration are common.
Also known as:
Linch pin, ring lock pin, spring-lock pin, hitch pin retainer, implement retainer pin, locking ring pin, snap-ring lock pin. These terms are often used for the same style of quick-locking pin with a sprung ring used to retain a shaft or fastening in place under vibration.
