Timco Classic A4 Stainless Steel Screws 3.5x20mm, 200pc, PZ Double Countersunk
Marine-grade A4 stainless steel screws for corrosive environments. Double countersunk, PZ drive, 200pc pack. Ideal for timber and plastic.
Timco Classic Multi-Purpose Screws offer superior performance with marine-grade A4 stainless steel construction, making them ideal for use in coastal and highly corrosive environments. These screws are perfect for fixing to softwoods, hardwoods (when pre-drilled), chipboard, MDF, and plastic.
The double countersunk head reduces the likelihood of head shear and ensures a flush finish, while the 40° deep single thread provides a secure fixing with high pull-out resistance. A single slash on 25mm+ screws reduces torque and prevents timber splitting when inserting close to the edge.
All screws up to 75mm in length are fully threaded, while those 80mm and above have a 70mm thread length for optimal grip and stability.
