The Diall Machine Screw & Nut set is an essential hardware pack for DIY enthusiasts and professionals alike, designed to provide a secure, reliable fastening solution for various household and furniture assembly projects. Constructed from high-quality carbon steel with a zinc-plated finish, these fasteners offer excellent corrosion resistance and durability; however, users should ensure they are not used in high-moisture or exterior environments where stainless steel would be more appropriate for preventing long-term rust.

No, these are constructed from zinc-plated carbon steel, which is strong but not as corrosion-resistant as stainless steel.
You will need a screwdriver or a wrench depending on the head style, and potentially a drill for creating pilot holes.
It is not recommended, as outdoor exposure will likely compromise the zinc plating and lead to rust over time.
Each pack contains 20 bolts and 20 corresponding nuts.
The bolts have a standard diameter of 6mm.
Yes, if you wish to change their appearance, you can lightly sand the zinc finish and apply a metal-suitable primer and paint.
Verify that the pilot hole is correctly sized and check for any debris or metal shavings within the threads of the nut.
Ensure you are using the correct size driver bit and maintain downward pressure while rotating to keep the bit fully engaged.
Ensure the bolt is not cross-threaded; remove the nut, check the threads for damage, and restart the threading process slowly.
To achieve the best results, start by clearing the bolt path of any wood debris or metallic burrs. When tightening, apply steady pressure to ensure the threads bite correctly without cross-threading. If installing into soft timber, it is recommended to drill a small pilot hole first to prevent the wood from splitting under the tension of the 70mm shank. Since these bolts are zinc-plated, avoid using aggressive chemical cleaners or abrasive scouring pads, as these can strip the protective layer and expose the bare carbon steel to air and moisture. If the bolts are intended for use in high-humidity areas, apply a light coat of machine oil or a corrosion inhibitor during installation to extend their lifespan.
