The Prinsu Carriage Bolts and Washers are the hardware you need to mount accessories and gear directly to your Prinsu roof rack crossbars. Each pack includes 10 sets of quarter-inch 20 stainless carriage bolts, quarter-inch black zinc washers, and quarter-inch black zinc nylock nuts, giving you everything required to secure a wide range of add-ons to your existing Prinsu rack setup. Whether you are adding a light bar, mounting a cargo basket, or attaching other aftermarket accessories, these bolts are the right hardware for the job.
Prinsu Carriage Bolts and Washers Fit All Prinsu Rack Crossbars
These carriage bolts are designed to fit directly into the drop points built into every Prinsu rack crossbar. The drop point system is what makes Prinsu racks so easy to work with, and these bolts are machined to the correct size to seat cleanly in those slots without wobble or play. Once seated, the bolt head locks in place against the crossbar so you can tighten the nut from below without needing a second tool to hold the bolt steady. The result is a fast and secure connection every time.
Stainless Steel Construction for Corrosion Resistance
The carriage bolts in this pack are made from stainless steel, which gives them strong resistance to rust and corrosion even when exposed to rain, humidity, and road salt over time. The black zinc washers and nylock nuts complete the hardware set with finishes that resist oxidation and hold their appearance through regular outdoor use. Using quality hardware matters when your accessories are mounted on top of your vehicle at highway speeds, and these components are built to stay tight and corrosion-free for the long term.
Nylock Nuts Keep Everything Locked in Place
The included black zinc nylock nuts are an important part of what makes this hardware set reliable for roof rack use. Nylock nuts use a nylon insert that grips the bolt threads and resists loosening from vibration. On a roof rack that sees regular highway driving and off-road use, vibration is constant. Standard nuts can back off over time, but nylock nuts stay put once torqued to the correct specification. This small detail makes a real difference in keeping your accessories mounted securely over thousands of miles.
A Practical Pack Size for Ongoing Builds
Each pack contains 10 sets of bolts, washers, and nuts, giving you enough hardware to mount multiple accessories at once or keep extras on hand for future additions to your Prinsu rack. If you are building out your rack over time or adding new gear before each season, having a pack of these on hand means you are never stuck waiting for hardware when you are ready to install something new.
