Nylon Head Screws & Quick Release Pins

What Are Nylon Head Screws & Quick Release Pins?

When it comes to keeping a bimini top or boat cover secure, the small hardware components that hold everything together matter more than most boaters realize. Nylon head screws and quick release pins are the unsung heroes of bimini top systems — they lock jaw slides, deck hinges, and frame components into place, and they allow the entire top to be raised, lowered, or removed without reaching for a drill or a wrench.

Nylon head screws are typically injection-molded from UV-resistant nylon and feature an oversized knob-style head that can be tightened or loosened by hand. The nylon head screw secures the bimini top into a desired position, and the knobs on the screw head make loosening and tightening easy. This hand-friendly design is especially useful on the water, where grabbing a screwdriver is inconvenient and time is better spent enjoying the day.

The Role of Quick Release Pins

Quick release pins take convenience a step further. Quick release pins allow you to remove your top without unscrewing it — simply insert the pins into your deck hinges instead of screws, and you have an easy way to install and remove your top with no need for a drill. This makes them a popular upgrade for boaters who frequently fold down or completely remove their bimini top for trailering, storage, or open-water cruising.

Quick release pins typically feature a nylon cap for a secure grip along with a steel ball lock for added security and easy operation — designed for quick and efficient release, making them ideal for marine applications where frequent adjustments are necessary.

Nylon vs. Stainless: Choosing the Right Material

Not all bimini hardware needs to be stainless steel. Molded nylon is considerably less expensive and perfectly suitable for light to moderate recreational use, especially on boats stored out of the elements. However, it's worth understanding the trade-offs: nylon fittings are impervious to rust but are not as strong as stainless fittings and tend to deteriorate over time from UV and weather exposure. Nylon fittings are acceptable for lighter-duty use, but for larger tops, higher speeds, rougher water, and more frequent use, stainless fittings are worth the added cost.

When shopping for replacement nylon head screws or quick release pins, be sure to verify compatibility with your existing hardware. There are several different sizes and shapes of tubing used to make bimini tops — the most common being 7/8" O.D. and 1" O.D. round aluminum or stainless steel tubing. Measure your bimini tubing carefully before ordering parts.
