Why Carbon Steel & Zinc Plating Outperform Stainless for Lynch Pins
While stainless steel is excellent for corrosion resistance, it is softer than heat-treated carbon steel and can deform under the repeated shear loads that lynch pins experience in agricultural and towing applications. Our carbon steel pins are heat-treated to 45-50 HRC — hard enough to resist bending and shearing, but not so hard that they become brittle and snap. The bright zinc plating provides the corrosion resistance that carbon steel lacks on its own, creating a pin that combines the strength of hardened steel with the weather resistance needed for outdoor equipment. The spring steel retaining ring is a separate material choice — spring steel is specifically formulated to maintain its tension through thousands of open/close cycles without taking a permanent set or losing clamping force.
Frequently Asked Questions
What size hitch pins do these fit?
These 1/5-inch × 1-3/5-inch lynch pins fit 1/4-inch to 3/8-inch diameter hitch pins with standard cross-hole spacing. They are designed for standard agricultural, trailer, and towing hardware — not for heavy equipment pins over 1/2-inch diameter.
Will these rust over time?
The zinc plating provides excellent corrosion resistance for normal outdoor use. For marine/saltwater environments, applying a light coat of oil, fluid film, or anti-seize will extend the service life significantly. The spring steel rings are the most susceptible component — lubricate them periodically in harsh environments.
Will vibration cause the ring to loosen?
No. The spring steel retaining rings are specifically engineered with high clamping tension to resist vibration-induced loosening. This design has been proven reliable in agricultural equipment for decades, where constant vibration from diesel engines and rough terrain would quickly shake loose an inferior clip.
Can I use these for a tractor 3-point hitch?
Yes. These lynch pins are ideal for securing the lift arm pins and top link pins on Category 1 and Category 2 3-point hitches. The 20-pack quantity ensures you have spares when one goes missing in the field.
Are these the same size as the ones that came with my trailer?
Most standard trailers use 1/4-inch or 5/16-inch hitch pins with matching lynch pin clips. These 1/5-inch × 1-3/5-inch pins are the standard replacement size. Measure your existing pin's cross-hole diameter to confirm before ordering.
