Pintle Hooks & Mounts – RV Trader Accessories Store

A pintle hook is only as reliable as the hardware holding it to the mount. Loose, corroded, or under-spec mounting bolts are the weak point in an otherwise heavy-duty connection - and on a pintle setup that's doing real towing work, that's not a variable worth leaving to chance.

This collection carries Rigid Hitch pintle mount bolt kits in every common fastener size, in Grade 8 hardened steel with matching nuts and washers. All five products are in-stock and ready to ship.

What's in This Collection

Pintle mounting hardware in this collection covers the bolt sizes used across the most common receiver-mount and plate-mount pintle hook configurations:

• 1/2" Pintle Mount Bolt Kit - Set of 4 bolts, washers, and nuts
• 9/16" Pintle Mount Bolt Kit - Set of 4 bolts, nuts, and washers
• 5/8" Pintle Mount Bolt Kit - Full set with nuts and washers
• 3/4" Pintle Mount Bolt Kit - For larger commercial-duty pintle mount applications
• 10-Pack Pintle Hook Mounting Bolt Kit - 1/2" Grade 8 bolts, nuts, and washers in bulk; appropriate for shops, fleet maintenance, or anyone replacing hardware across multiple trailers at once

All hardware is Grade 8 - the correct specification for towing fasteners. Substituting lower-grade hardware on a pintle mount is a common mistake that reduces the connection's actual rated capacity.

Choosing the Right Bolt Size

Pintle hook mounting bolt size is determined by the holes in your pintle mount plate or receiver adapter - measure the existing bolt hole diameter to confirm before ordering. The four sizes here (1/2", 9/16", 5/8", and 3/4") cover the range found on standard receiver-mounted pintle mounts and direct plate-mount pintle hooks used in agricultural, construction, and utility towing applications.

If you're replacing worn or corroded hardware after a season of heavy use, replace all mounting bolts at the same time rather than swapping only the visibly damaged ones. Fasteners on a pintle mount are under repeated dynamic load - hardware that isn't visibly damaged can still be fatigued.

FAQ

What grade bolts should I use for a pintle mount? Grade 8 is the correct specification for pintle hook mounting hardware. Grade 5 bolts - commonly available at hardware stores - have lower tensile and yield strength and are not appropriate for towing fastener applications. All bolt kits in this collection are Grade 8.

What size bolts does a pintle mount use? Pintle mount bolt size depends on the specific mount. Common sizes are 1/2", 9/16", 5/8", and 3/4". Measure the hole diameter on your mount plate before ordering - all four sizes are available here, along with a 10-pack of 1/2" hardware for bulk replacement needs.

What is a pintle hitch used for? A pintle hitch uses a hook-and-lunette-ring connection instead of a ball and coupler. It provides more vertical and horizontal articulation than a ball hitch, making it the standard for construction equipment, agricultural trailers, military applications, and off-road towing where uneven terrain and heavy loads are both factors. For the full range of pintle hooks, mounts, and combination pintle-ball hitches, the trailer hitches collection carries the broader selection.

Need pintle hooks or receiver mounts in addition to mounting hardware? The trailer hitches collection has pintle hooks, pintle mounts, and combination pintle-ball units for both receiver-mount and plate-mount applications. For the tow vehicle side of the setup, receiver hitches covers vehicle-specific Class III through V hitches.
