Macsim's batten screw range offers a choice of sizes, drive types and finishes for timber fixing jobs. Whether you are working indoors or outside, you can choose a screw to suit the connection, the timber and the conditions it will be exposed to.

The Macsim batten screw range includes:

  • Drive options - Hex and star drives, with the driver size depending on the product.
  • Countersinking heads - Self-embedding bugle-head options help create a neat, countersunk finish in timber.
  • A choice of sizes - Different lengths and gauges let you select a fixing to suit the connection.
  • Materials and finishes - Zinc-plated, galvanised, stainless steel and coated options for different applications.

Drive sizes, point designs and corrosion protection vary between products. Check the individual screw's specifications for the correct driver bit, installation method and suitability for treated timber or exposed locations.
