GRK FIN/Trim 305 Stainless Steel screws provide superior corrosion resistance for high moisture environments. 305 stainless steel screws are for applications that require superior corrosion resistance in exterior environments with high moisture content, such as docks, boardwalks, pools and hot tubs. 305 stainless steel is also for use with cedar, redwood, and various wood species that have higher acid content.
GRK's FIN/TRIM head screws are an excellent choice for most trim carpentry applications. They have the smallest screw head available with lengths from 1-1/4-inch to 5-inch. Most material splitting is prevented by the Trim head screw's small head and W-cut thread design. Pre-drilling is usually only necessary in extreme hardwoods like Mahogany or Ipe'. Some sizes are availabele in PHEINOX stainless steel.
