Frequently Asked Questions
Q: What are M6 M7 M8 left-hand thread hex flange saw blade screws used for?
A: These left-hand thread hex flange screws are designed to secure saw blades and cutting discs onto rotary cutting machines such as angle grinders and circular saws. The left-hand thread is engineered to tighten — rather than loosen — as the blade spins, keeping the blade firmly in place during operation. Available in M6, M7, and M8 sizes to suit a variety of cutting machine arbors.
Q: Why does a saw blade screw use a left-hand thread?
A: Cutting machines rotate in a direction that would naturally unscrew a standard right-hand thread fastener over time. A left-hand thread counteracts this rotation, meaning the mechanical action of the machine actually keeps the screw tighter during use — a critical safety and performance feature for any rotating blade application.
Q: What material are these hex flange screws made from?
A: These screws are manufactured from high-strength carbon steel with a galvanized treatment. Carbon steel provides excellent tensile strength and hardness suitable for demanding cutting applications, while the galvanized coating adds corrosion resistance for longer service life in workshop environments.
Q: How many screws come in one pack, and which sizes are available?
A: Each pack contains 10 screws. You can choose from three sizes: M6 (6mm), M7 (7mm), or M8 (8mm) — select the size that matches your cutting machine's arbor specification.
