Description

The Allstar ALL18633 countersunk bolt kit provides a clean, flush-mounted appearance for various applications. Each kit contains specially designed aluminum washers that enable socket head fasteners to sit flush with the mounting surface. This eliminates protruding hardware and creates a smooth, finished look, enhancing both aesthetics and safety. These versatile kits are ideal for a wide range of uses, such as securely mounting exterior components like roofs, side skirts, and spoilers. They are also well-suited for interior applications, like replacing sharp-edged fasteners within a cockpit to prevent injury. The kit includes the necessary washers, bolts, and nyloc nuts for a complete installation. The bolt specifications include a 1/4-20 thread size, a 1-inch washer diameter, and a flat head style. The exterior finish is machined, and the manufacturer grade is premium. These bolts are constructed from alloy steel and come in a black finish.
