Wood Screw A4

The wood screw is one of the most common types of fasteners, used across a wide range of applications: in shipbuilding and pool construction, as well as in the assembly of instruments and automation equipment in various industries.

Wood screw A4 is made of austenitic stainless steel containing 2-3% molybdenum. Compared to standard or zinc-plated hardware, it offers higher strength and resistance to:

• corrosion;
• acids;
• chlorine-containing compounds;
• seawater.

Wood screw A4 provides a reliable connection both for materials of uniform structure and for dissimilar materials. This type of fastener is used in construction and repair work.

The range of A4 wood screws varies by length, shank and head diameter, and thread pitch. The head can be round, flat or hexagonal on an exposed fastener, or with internal faces on a countersunk one. The head features either a straight or cross-shaped slot — for driving with a screwdriver or a power driver.
