Material: carbon steel, blue and white zinc plating
Product length: 34.8*21.8mm/1.37*0.86inch
The 1-1 / 4" #8 thick hole screw with washer head prevents overtightening of the bottom of the pocket, which is especially important in composite and plywood workpieces.
The self-tapping 17-type auger tip does not require pre-drilling, and its larger diameter steel shank can form a screw that is hard to break. This bag has 530 hole screws.
