Perko Hasps

Perko Marine Hasps: Secure, Saltwater-Ready Hardware from a Century-Old American Maker

When it comes to securing hatches, compartments, and storage doors aboard a vessel, the hasp is a small but mission-critical piece of hardware. Exposure to saltwater, UV rays, and constant vibration quickly reveals the difference between a marine-grade hasp and a cheap substitute. That's where Perko has earned its reputation — by engineering hardware that holds up where it counts.

Hasps in the Perko lineup are designed specifically for the demands of the marine environment. Perko offers marine-grade stainless steel hasps with a lockable feature , giving boat owners double-layer security: the hasp itself closes the staple, and a padlock can be added for an additional layer of protection. The Perko chrome plated zinc hasp is a durable and secure door latch designed to provide reliable protection, made from high-quality chrome plated zinc alloy that offers excellent strength and resistance to corrosion.

Material Options Built for the Sea

Perko hasps are available in two primary material constructions to match different applications and budgets:

• Marine-Grade Stainless Steel – Marine-grade stainless steel construction delivers maximum corrosion resistance, making these hasps ideal for exposed deck hardware, high-moisture bilge access panels, and any fitting that faces the harshest saltwater conditions.
• Chrome Plated Zinc Alloy – Chrome plated zinc alloy provides enhanced durability and resistance to rust, with a closed length of 3 inches, a width of 1 inch, and a padlock clearance of 1/4 inch for easy use with compatible padlocks. This option brings a polished, classic look well-suited to cabin doors and interior-facing storage.

Why Trust Perko for Marine Hardware?

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 isn't accidental — it's the result of an unwavering commitment to manufacturing integrity.

Perko does just about everything itself, from engineering and building tooling to chrome plating, casting, injection molding, and metal fabrication. Perko products are manufactured in the United States using American-sourced raw materials, maintaining a strong "Made in America" commitment throughout their operations. Their ISO 9001:2015 certification reflects a dedication to excellence across all operations.

For a boater or builder sourcing closure hardware, this means every Perko hasp — whether stainless steel or chrome zinc — is produced under the same rigorous quality controls that govern the brand's navigation lights, deck plates, and latches. Perko's locks and latches are crafted with a commitment to quality and innovation, designed to withstand the harshest marine environments, their durability a testament to decades of experience in the marine industry.

The Right Hasp for Your Vessel

Choosing a hasp comes down to the installation environment and security requirements. Exposed cockpit lockers and deck-level compartments benefit most from stainless steel construction, while chrome zinc models are an excellent fit for interior cabinet doors, helm consoles, and livewell lids where a refined finish matters as much as function. Either way, Perko's product line — which includes locks, latches, hinges, and hasps — spans over 1,000 individual products , meaning replacement parts and compatible hardware are always within reach.
