Double countersunk to reduce the likelihood of head shear and assists with countersinking patented lubrication to enhance the screw insertion and provides greater resistance to corrosion 40-degree deep single thread to provide secure fixing with high pull out resistance. Surface hardened to prevent torque shearing. Performs efficiently in softwood, hardwood, chipboard, MDF, plastic and thin sheet material A2 grade stainless steel, ideal for highly corrosive environments or in timber with high acid content.
It is a common misconception that stainless steel is stronger than regular steel. Therefore, when compared to regular steel, the stainless alloys used in bolts are slightly stronger than an un-hardened (grade 2) steel but significantly weaker than hardened steel fasteners.
There are many stainless steel screws uses, including building decking to other outdoor jobs. Stainless steel screws are suitable for use in areas of high pollution, such as inner cities and near major traffic routes, and also near coastal regions and areas that are damp in general.
Stainless steel lasts much longer than galvanized steel, so when the longevity of the building project is of importance, using stainless steel is recommended. Stainless steel is much stronger than plain steel hot-dip galvanized.
These screws are multipurpose can be used in a range of materials as well as having a variety of head types available for the type of finish you are looking for. Suitable for use with screwdrivers, combi drills and impact drivers. Stainless steel screws are used in areas likely to continually be moist as they are notably known for their resistance to corrosion.
