Perko Barrel Bolts

Perko Barrel Bolts: Century-Proven Security for Marine Cabinetry

When it comes to keeping doors, lockers, and hatches secured aboard a vessel, the hardware has to work as hard as the rest of the boat. Salt air, vibration, and constant moisture will quickly expose any weakness in poorly made cabinet hardware — and that's exactly where Perko separates itself from the crowd. Barrel bolts may seem like a simple piece of hardware, but Perko's marine-grade approach to their design and construction makes them a cut above generic alternatives found at hardware stores.

Why Perko Barrel Bolts Are Built for the Marine Environment

Unless specifically built to withstand the rigors of the marine environment, barrel bolts and other types of cabinet fastenings can soon lose their luster — but boaters can count on Perko for tough and attractive hardware that stands the test of time. This commitment to marine-specific engineering is evident in every detail of their barrel bolt lineup.

Perko's barrel bolts feature a chrome-plated bronze body and high-impact black nylon bulkhead keeper, a 3/8" diameter bolt, and a bulkhead keeper that easily installs in a 5/8" hole — and each includes a friction pad to eliminate rattle and provide smooth operation. That anti-rattle friction pad is more than a convenience feature; on a vessel that's constantly moving with wave action and engine vibration, a rattling bolt quickly becomes an annoyance and eventually a distraction. Perko's integral design solves the problem at the source.

Slim and Standard Barrel Bolt Lines

Available with either visible or hidden mounting holes, Slim Barrel Bolts from Perko fulfill a wide variety of applications — strong and reliable, they're ideal for securing doors, cabinets, and lockers, and chrome-plated zinc alloy construction ensures the bolts retain their shiny good looks. Whether you're fitting out a new build or replacing aging hardware, both styles accommodate different aesthetic preferences and installation requirements. Both types feature an integral friction pad that eliminates rattle while providing smooth operation.

For heavier-duty applications, Perko's classic Figure No. 0947 series steps up with a cast bronze chrome-plated body, offering even greater corrosion resistance and structural integrity. These heavy-duty barrel bolts are cast bronze chrome-plated and countersunk for #6 screws, making them well-suited for high-traffic cabin doors and storage compartments that see daily use.

Backed by Over a Century of American Manufacturing

Since its inception in 1907, Perko has grown into a fifth-generation American marine manufacturer known for high-quality marine lighting, deck hardware, and emissions-compliant fuel-system components for recreational and commercial boats. That longevity matters when you're choosing hardware for a vessel — it means decades of refinement in material selection, manufacturing tolerances, and real-world performance feedback. A key part of the Perko formula is the commitment that all products are made in the United States, with raw materials such as sheet metal, bronze, and zinc sourced from American manufacturers.

Perko's ISO 9001:2015 certification reflects a dedication to excellence across all operations, giving buyers confidence that every barrel bolt that leaves the factory meets consistent quality standards. For boaters who demand hardware that looks great on day one and still functions flawlessly years later, Perko's barrel bolts represent a reliable, time-tested solution backed by one of marine hardware's most trusted names.
