Malco Zip-In Screws Hw8X1 2Zt

Malco HW8X1/2ZT - #8 x 1/2" Hex Zip-In Screws (Tub of 1,000) Product Description: 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. * Undercut-indented hex washer slotted head * Bright Zinc Plated * Burr Fee * Full 1/4" (no 8) head will not strip out of hex driver opening * One 1/4" hex driver accommodates all sizes * Undercut - always seats flush * Some screws sizes available in pails. * Trademarked & Patented Head Markings indicate one and only genuine Zip-ins.
