This product range is available with Phillips, Pozi, Torx and Square drive configurations. Buyers can select the drive according to the required driver interface and fastening application.
Both fine and coarse thread versions are available. Thread selection should be matched to the substrate and fastening requirement. The threaded profile provides mechanical engagement in suitable wood and panel materials.
The fasteners use 15° plastic sheet collation for sequential feeding through compatible pneumatic coil equipment. The plastic carrier keeps the fasteners aligned in the coil and separates during installation.
Tool compatibility must be checked using the complete specification, including 15° plastic sheet collation, 3.5mm diameter, 40mm length, head geometry and coil configuration. A compatible brand name alone does not confirm that every nailer model can use this fastener.
