## Features

- A Hexagon Bolt is a threaded fastener with a hexagonal head shape, and are designed to be installed using a spanner. Hexagon bolts are favoured for their robust shape, which makes them suitable for more heavy-duty fastening applications. Hexagon bolts are also generally available in larger sizes than alternative fasteners.
- As their name suggests, Full Thread Hexagon Bolts are fully threaded. This type of bolt is required when the shaft of a fastener is being inserted completely into a threaded hole. Fully Threaded Bolts are often used to securely fasten two threaded sections together.
- Made from 18-8 stainless steel, FullerkregⓇ brand screws have good chemical resistance and may be mildly magnetic. Length is measured from under the head.
- Screws that meet ASME specifications comply with these dimensional standards.DIMENSIONS: Diameter: 1/4" | Length: 2-1/2" | Thread Type: 20 tpi Coarse Thread (Standard)
- Package includes ten each of bolts, hex nuts , Flat & Lock washers
