TIMCO Classic Multi Purpose Screws 3.5 x 40 A2 Stainless Steel Box of 200

The Classic Multi-Purpose Screw, manufactured from A2 Stainless Steel, is the ideal fastening solution for projects requiring exceptional corrosion resistance. Designed for use across a variety of materials, including softwoods, hardwoods (when pre-drilled), chipboard, MDF, and plastic, this screw is indispensable in environments that pose a risk of corrosion. In particular, it is highly recommended for applications involving naturally corrosive materials such as Green Oak.

One of the standout features of the Classic Multi-Purpose Screw is its double countersunk head design. This innovative feature significantly reduces the likelihood of head shear while facilitating an effective countersink. The screw incorporates a 40° deep single thread which provides a secure fixing with impressive pull-out resistance, ensuring that your fastenings remain stable under stress. For sizes up to and including 75mm, the screw is fully threaded, while screws measuring 80mm and above feature a robust 70mm thread length.

In terms of ease of use, the screw boasts a 25° sharp point that aids in effortless penetration into various materials. This sharp point, combined with a special thread configuration, optimizes performance and enhances pull-out resistance, making the Classic Multi-Purpose Screw a reliable choice for both professional and DIY applications. The surface of the screw has been hardened up to 750 HV, which prevents torque shearing, further enhancing its durability.

The screw also benefits from a patented molecular lubrication, designed to improve insertion time while providing an additional layer of resistance against corrosion. This characteristic is particularly essential in areas with aggressive environments, ensuring longevity and reliability in your fastening projects.
