SWC

Structural Countersunk Wood Screw

SWC is a countersunk structural screw designed for load-bearing wood structures. The SWC screw has a milling thread to allow for smoothdriving of the shank. The countersunk head gives flush fitting while allowing the wood members to close up firmly.

Application

Application:

Wood to wood

advantage

The countersunk head with milling ribs on the underside of the head can be
and flush with the surface of the wood, creating a harmonious appearance.

The cutting point design in combination with the reaming shank ensures efficient and
smooth screwing with a simultaneous minimization of the
insertion resistance and reducing the splitting effect.
