Weigh Safe Hitch Locking Pin Stainless Steel for 2", 2.5" & 3" Receivers — Keyed Lock & Dust Cover, 5/8" Shaft

The Weigh Safe Hitch Locking Pin is a heavy-duty stainless steel towing pin with an integrated dust cover that secures trailer connections for 2", 2.5" and 3" receivers.

Built to replace flimsy cotter pins and low-grade hardware, this locking pin is a simple, durable upgrade for anyone who tows regularly. Crafted from corrosion-resistant stainless steel and sized to standard hitch dimensions, it helps protect your trailer connection from theft and the elements while fitting the most common receiver sizes. The dust cover shields the locking mechanism from dirt, salt, and moisture to keep the pin operating smoothly season after season.

How does this hitch pin improve towing security?

Compared with a basic pin or clip, the Weigh Safe locking pin provides a keyed lock that makes accidental uncoupling or casual theft far less likely. The solid stainless steel shaft resists bending under load and the locking head keeps the pin from backing out during travel. For peace of mind on long hauls or overnight stops, the lock adds an important layer of protection.

• Keyed lock mechanism prevents unauthorized removal
• 5/8" diameter shaft resists shear and bending
• Locking head secures pin against vibration and road shock

Will this pin fit my trailer receiver and what are its exact dimensions?

The Weigh Safe pin is made to work with the most common receiver tube sizes—2", 2.5" and 3"—so it covers a wide range of towing setups. Its shaft measures 3-1/2" long with a 5/8" diameter to match standard hitchhole spacing and strength requirements. Always verify receiver wall thickness and hole spacing on your trailer for compatibility, but this pin fits the majority of consumer and many commercial setups.

• Fits 2", 2.5", and 3" receiver tubes
• Shaft length: 3-1/2" for standard hitch clearance
• Shaft diameter: 5/8" to match common hitch holes

How does the stainless steel construction and dust cover help over time?

Stainless steel provides natural resistance to rust and corrosion, which is critical when exposed to road salt, rain, and snow. The included dust cover keeps grit and moisture away from the lock cylinder, reducing the chance of freezing or seizing. Together these features extend the working life of the pin and lower maintenance needs compared with untreated metal pins.

• 316-grade stainless properties resist corrosion in harsh conditions
• Dust cover prevents debris buildup in the lock cylinder
• Less frequent lubrication and fewer frozen locks in winter

How easy is it to install and use during routine trailer hookup?

Installation is straightforward: slide the pin through the hitch and receiver, then turn the keyed lock to secure it. The design is meant for quick operation while providing a secure hold—no special tools required for daily use. The dust cover remains in place to protect the lock head when not in use, and the compact size stores easily when detached.

• Tool-free installation—insert pin and lock with supplied keys
• Compact head profile clears most hitch covers and accessories
• Dust cover snaps on for storage and protection between uses

Who is this for? The Weigh Safe Hitch Locking Pin is intended for recreational vehicle owners, contractors, landscapers, and anyone who tows trailers, campers, boats, or cargo and wants a reliable, low-maintenance locking solution. It’s a suitable upgrade for owners replacing cotter pins or inferior locks and for those who need a corrosion-resistant pin that fits multiple receiver sizes. If you want a straightforward, durable way to secure your hitch and reduce lock maintenance across seasons, this pin is designed for you.
