CZC AUTO 5/8" Hitch Receiver Pin Lock 4-Pack — keyed-alike, 3.5" length for 2" & 2-1/2" Class III/IV receivers, weather-resistant

The CZC AUTO 5/8" hitch receiver pin lock is a keyed-alike, heavy-duty trailer lockset designed to secure 2" and 2-1/2" Class III/IV receivers for racks, balls, trays, and tow accessories.

Keep your trailer attachment points protected with a set of four CZC AUTO dogbone-style receiver locks that use a 5/8" hardened pin and a 3-1/2" effective length. Each lock features a rotating head, rubber-sealed key cap and zinc-alloy core built into an electrophoretic painted carbon-steel body for weather resistance. The set ships keyed alike (8 keys total) so every lock in the pack opens with the same key for fast, practical access.

How will this lock fit my hitch receiver?

The lock is engineered specifically for Class III and IV receivers sized 2" and 2-1/2". With a 5/8" diameter pin and 3-1/2" effective length it suits most dogbone-style coupling points and common hitch-mounted accessories.

• Pin diameter: 5/8" (standard for many trailer hitches)
• Effective length: 3-1/2" to span receiver tubes and attachments
• Compatible with bike racks, cargo trays, hitch balls and tow ropes
• Intended for Class III and Class IV 2" and 2-1/2" receivers

How easy is it to use every day?

CZC AUTO focused on straightforward operation: insert the pin, turn the tubular key, then pull the head to confirm engagement. Each lock includes two keys and the set is keyed alike so you don't juggle different keys for multiple locks.

• Two keys per lock, eight keys total for the 4-pack
• Quick-rotate head for simple locking and removal
• Pull-test after locking provides a fast security check
• Rubber key cap prevents dirt and moisture in the keyway

What materials and weather protections are included?

The body is made from carbon steel with an electrophoretic finish to resist corrosion and reduce visible wear. A zinc-alloy lock core and a sealed tubular key channel help keep internal parts operating in wet or dusty conditions.

• Carbon-steel construction for strength and impact resistance
• Electrophoretic paint reduces rust and surface degradation
• Updated tubular keyhole and zinc-alloy core for reliable turning
• All-weather rubber cap shields the key slot from moisture
