Bit-Tip has a wide range of industry applications. Select the Bit-Tip that's right for the job. Point length will determine metal thickness that can be drilled, tapped and fastened. Also, plywood, soft wood, composition board, drywall, insulation and laminates may be fastened to metal framing or components. Made from strong, high quality, specially heat treated steel. Bit-Tip self drilling and tapping screws are precision cold forged insuring uniformity of dimension and drill point contours. The versatile Bit-Tip screw is an excellent replacement for fastening operations now using rivets, nuts and bolts, spot welds or adhesives. Bit-Tip also eliminates the need for costly auxiliary fastening equipment such as drill bits, taps and welding equipment.

Malco Zip-In HW8x1-1/2ZWT White Painted Steel Indented Hexagonal Washer A unique thread design and quality controlled manufacture spell the Zip-In difference. Zip-In's sophisticated heat treat process allows the screw to taper to a fine, sharp point without sacrificing critical point strength. A single starting thread is formed down to the very tip of the point and is the source of Zip-In's penetrating power. A second thread above the point engages after initial penetration and drills in the screw double fast. Zip-In screws are faster driving, with a greater capacity for fastening heavier gauges of sheet metal than any other self-piercing type.Sid Harvey Item #:HW8x1-1/2ZWT: Replaces Part #:'s : 13314,
