Wellmax Trailer Hitch Pin Assortment 20-Piece — 1/4", 5/16", 3/8" Gold Zinc, Squared & Arched Latches

Wellmax 20-piece trailer hitch pin assortment provides a complete set of zinc-plated safety pins in three diameters to secure couplers, jacks, and PTO accessories for towing and farm equipment.

Whether you tow occasionally or work with implements every day, having the right size hitch pin on hand prevents delays and keeps connections stable. This Wellmax kit contains 20 heavy-duty pins in both squared and arched latch styles, finished in a corrosion-resistant gold zinc plating so they withstand outdoor exposure and repeated use.

Which pin sizes and styles are included in the set?

The assortment covers common shaft diameters to match a wide range of couplers and accessory holes. You get multiple pieces of each size and two latch shapes so you can pick the best fit and locking action for the application.

• 6 × 1/4" squared-pin style for snug, flat-sided holes
• 6 × 1/4" arched-pin style for faster insertion and retention
• 4 × 5/16" squared-pin style for medium-duty connections
• 4 × 3/8" arched-pin style for heavier shafts and vibration resistance

How durable and weather-resistant are these Wellmax pins?

Each pin is manufactured from quality steel and carbon-steel components, then zinc-plated to reduce surface rust and corrosion. The plating plus the solid construction lets these pins perform outdoors in wet or dusty conditions without rapid degradation.

• Zinc-plated finish provides corrosion resistance and a gold appearance
• Steel and carbon-steel bodies resist bending under normal towing loads
• Spring-steel wire latches maintain tension for secure locking

Are the latch pins easy to use and will they stay secure while towing?

The semi-flexible spring-steel wire latch is designed for quick insertion and reliable retention. When placed into the mating hook slot, the wire latch snaps into position and holds the pin from backing out, reducing rattle and accidental release under vibration.

• Spring-wire latch snaps tight into corresponding hook slots
• Rounded arched styles slide in and out quickly when needed
• Squared styles provide a more stable, anti-rotation fit for flange-style holes

What applications are these pins suitable for?

This assortment is versatile enough for towing, agriculture, landscaping, marine hookups, and general equipment attachment tasks. Use them on trailer couplers, jack wheels, agricultural implements, PTO accessories, or any application that accepts the listed diameters.

• Trailer couplers and safety chains
• Trailer jack wheels and swivels
• Farm implements, plows, and hitch-mounted tools
• PTO and general utility equipment attachments

Who is this for? This Wellmax 20-piece kit is aimed at trailers owners, landscapers, farmers, and DIYers who prefer to be prepared. If you frequently switch accessories, maintain multiple trailers, or need a small inventory of reliable locking pins for outdoor gear, this assortment gives you the common sizes and latch styles to keep equipment connected and moving.
