Hvac Malco Sheet Metal Screws | 3/4″ (Length) 1/4″ (Head Size) Slotted Hex Washer Head Zip-In Sheet Metal Screws (5,000 Pack)

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.
