Stainless Steel Posi Head Countersunk Screw – M4 x 40mm – Box of 200

Ideal for use in sanitary locations and in marine environments- Stainless Steel does not corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments. Stainless steel is used where both the properties of steel and resistance to corrosion are required.

• Double countersunk reduces the likelihood of head shear and assists completion of countersinking
• 40° deep single thread to provide a secure fixing with high pull-out resistance
• Single slash on 25mm+ to reduce torque and the likelihood of the timber splitting when the screw is inserted close to the edge
• Fully threaded.
