Deargooday porkchop cap nut wrench for 1-1/2" (38mm) truck caps — steel, black coated, square-drive ready

This specialized wrench is built for technicians, truck owners, and fleet maintenance crews who work with older nut-and-thimble style semi-truck lug assemblies. Its porkchop profile slips over the rim lip and locks against the wheel so you can split cap studs from nuts without scoring rims or letting the wrench slip. Coated steel construction provides corrosion resistance and dependable strength for routine use on heavy vehicles.

How does this wrench keep the outer cap nut secure while I loosen the inner nut?

The porkchop shape features a lip that seats against the rim, creating a solid reaction point so the wrench resists rotation while torque is applied to the inner nut. You insert the wrench over the cap nut and press the lip into the wheel, then apply force to the square drive to break studs or turn nuts.

• Design seats against the rim to prevent slipping.
• Square-drive accommodation for standard impact or breaker bars.
• Works with cap studs and thimble-style lug systems.

Will this fit my truck’s caps and wheels?

This Deargooday tool is sized specifically for 1-1/2" (38mm) cap nuts common in older semi-truck dual-wheel assemblies. It is not a universal fit for every modern cap design, so confirm your cap nut diameter before purchase.

• Fits 1-1/2" (38mm) cap nuts only.
• Made for old nut-and-thimble style lug systems and dual wheels.
• Not recommended for non-cap or one-piece modern lug designs.

What materials and finish does it have, and how durable is it?

The wrench is manufactured from steel and finished with a black coating that helps resist rust and corrosion commonly encountered in road service. It’s engineered to withstand the high torque needed to split cap studs and to provide consistent performance in maintenance environments.

• Steel construction for strength and impact resistance.
• Black corrosion-resistant coating for longer life.
• Quality-controlled manufacture for dependable durability.

How simple is it to use in a roadside or shop setting?

Operation is straightforward: position the wrench so the lip bears on the wheel rim, then use a square-drive breaker bar or impact tool to apply torque to the cap or stud. The porkchop form keeps the tool from spinning, letting one person hold the outer cap while the inner nut is worked.

• Quick placement over the cap nut with positive rim engagement.
• Compatible with common square-drive tools for rapid use.
• Reduces the risk of wheel damage compared with improvised methods.

This Deargooday 30609 porkchop cap nut wrench also comes with a 30-day return policy and a 12-month warranty for customer peace of mind. If the tool doesn’t meet expectations, you can return it for a refund or warranty support.

Who is this for: technicians, owner-operators, and fleet mechanics who service older semi-trucks with nut-and-thimble dual-wheel configurations will find this tool useful. It’s aimed at professionals and serious DIYers who need a simple, robust way to hold outer cap nuts while breaking or turning inner nuts without damaging rims.
