Application

For indoor use in damp and wet areas (kitchen, bathroom etc.) and outdoor use with direct exposure to weather.

SPAX A2 stainless steel washer head 'construction use' screws are the solution for various joinery projects using wood - including fixing together battens and squared timbers.

Description

The washer head construction screw with universal applications and corrosion protection for use in damp/ wet areas or outdoor use.

Features and benefits:

  • No rust marks.
  • Long lasting.
  • Better tightening of connections including warped boards.
  • T STAR plus bit recess.
  • Pre-drilling recommended.
  • 4CUT point ensures safe fastening with low effort, reduces splitting of the wood and reduces the screwing-in torque required.
  • Quick and safe fastening.

The special power drive – T-STAR plus – is a so-called hexalobular socket. Compared to less precise drive types such as Philips or Phillips, the contact surface of our T-STAR plus is significantly larger, and the T-STAR plus bits always fit perfectly in the screw head. The resulting optimal, precise power transfer from screwdriver to screw with the T-STAR plus enables simple and extremely fast work, and is significantly more efficient than with any other drive.

In contrast to a partial thread, the full thread on most of SPAX’s full-thread screws extends the entire length, or almost the entire length, from the tip to the head. The more threads a screw has, the greater the tensile and compressive forces it can absorb. We take advantage of this, especially in structural timber construction, where full-thread screws are used for heavy-duty wood connections.

The 4CUT designation for the tip of the screws refers to the fact that it is not round, but square. These four edges displace the wood fibers during screwing, creating space for the screw's core diameter. This effectively reduces the otherwise unavoidable expansion pressure exerted by the core in the wood, preventing the wood from splitting open near the edges. The torque required by the cordless screwdriver is also reduced, as the screw core doesn't have to "squeeze" into the wood.

The abbreviation A2 for the stainless steel screws comes from the steel's alloy. ‘A’ stands for "austenite," a mixture of iron, carbon, and the alloying elements chromium, nickel, and molybdenum. The 2 (1-5) indicates the alloying grade, i.e., the chromium and nickel content.

A2 stainless steel screws offer high corrosion protection and medium strength. However, their resistance to seawater and acids is low. They are therefore used outdoors in areas far from the coast, where they provide long-lasting, reliable service.
