Understanding a drive’s purpose and the differences between drives will help you decide which style you should choose for your specific project. Slot This drive has a single horizontal indentation in the fastener head and is driven by a “common blade” or flat-bladed screwdriver.  […]

Selecting The Appropriate Fasteners For High-Temperature Applications

Fasteners need to perform reliably in all applications. It’s important to be aware of the factors that can affect that performance, particularly in high heat situations. Utilizing the wrong fasteners under high heat can cause weakening, disintegration or even vaporization.  Bolts can be made of a variety of materials, including carbon steel, alloy steel and stainless steel, but high-temperature applications call for iron, nickel and chromium-based alloys.   This awareness of fastener selection for high-heat applications […]
