What is the difference between a Type B and Type AB Self Tapping Screw?
Type B self tapping screws feature a blunt tip and coarse threads, making them ideal for use in softer materials such as plastics, wood, and thin sheet metal. Their design allows for better grip and thread engagement in these substrates, reducing the risk of stripping. On the other hand, Type AB self tapping screws combine the pointed tip of a Type A screw with the finer threads of a Type B. This hybrid design makes them more versatile, allowing for easier starting and a tighter fit in both soft and thin hard materials like aluminium and sheet metal. As a result, Type AB screws are often preferred for general-purpose fastening where a cleaner finish and more precise thread engagement are required.
Do I need a Pilot Hole for Self Tapping Screws?
Stainless self tapping screws: Drill a pilot hole between the screw's minor diameter (shaft) and major diameter (outer thread). The Pilot Hole should be slightly smaller than the screw's diameter. We stock a comprehensive range of self tapping screw sizes engineered for precise fastening across metals, plastics and composites in production and maintenance environments.
