Wellmax Trailer Hitch Pin Assortment 20-Pc Gold Zinc-Plated, 1/4–3/8 in Spring-Latch

If you tow trailers, work with agricultural implements, or keep utility gear around the yard, having a matched set of locking pins saves time and prevents lost trips. This Wellmax kit groups squared and arched designs across 1/4", 5/16", and 3/8" diameters so you can pick the right pin for couplers, hitch holes, jack wheels, and PTO attachments. Each pin uses a spring-steel wire latch for a snug, low-noise hold and a gold zinc-plated finish for corrosion resistance in outdoor conditions.

Which pin sizes and styles are included, and why does that matter?

The assortment contains specific counts and shapes to match common hitch and accessory requirements. Having both squared and arched latch styles across three diameters gives you flexibility when hardware tolerances and hole shapes vary.

• 6 × 1/4" squared-design pins for smaller couplers and implements
• 6 × 1/4" arched-design pins for rounded-receiver fittings
• 4 × 5/16" squared-design pins for medium-load applications
• 4 × 3/8" arched-design pins for heavier or thicker receivers

How do these pins lock and stay secure while towing?

Each Wellmax pin uses a semi-flexible spring steel wire latch that snaps into place when installed. The spring action keeps the pin from backing out under vibration and reduces rattle, while the straight shaft provides solid shear strength through the hitch or accessory hole.

• Spring-steel latch locks quickly and resists loosening
• Smooth shaft for easy insertion and reliable shear support
• Tight fit reduces noise during travel or fieldwork

Are these pins durable in wet or salty environments?

Yes — the pins are made from high-quality steel and carbon steel then zinc-plated with a golden finish to slow oxidation. Zinc plating protects the metal from rust and extends usable life in rain, coastal air, or seasonal storage where moisture is present.

• Zinc-plated surface resists corrosion and pitting
• Gold finish makes visual inspection for wear easier
• Suitable for outdoor storage and repeated use

What practical uses do these shaft locking pins have around the farm, shop, and home?

This assortment covers a wide range of everyday locking tasks — from trailer couplers and jack wheels to PTO accessories and gardening implements. The mix of sizes and latch styles means you can standardize a drawer or toolbox with spares for unexpected repairs or replacements.

• Trailer couplers, ball mounts, and receiver hitches
• Trailer jack wheels, implement linkages, and farm equipment
• PTO covers, truck bed accessories, and temporary clamps

Who is this for? The Wellmax 20-piece trailer hitch pin assortment is aimed at drivers, contractors, landscapers, and farmers who need durable, versatile locking pins on hand. It’s also useful for DIYers and fleet managers who prefer keeping multiple size options available to avoid downtime — a compact, corrosion-resistant kit that suits regular towing, outdoor work, and general equipment maintenance.
