Cross Recess Flat Head High Low Threads Confast Concrete Screws Square Cone Point
Cross Recess Flat Head Hi low Threads Confast Screws Square Cone Point for Concrete
Metal confast screws are made of carbon steel with harden treatment grade 6.8 , cross recess in the centre of the head and 90 degree countersunk head design for taper hole of material . confast screws with a square cone point that improves drilling perfromance and stop conrete screws to back out , self tapping threads with cutting line from begainning to end of the threads , this design is helping screws to fast to drill material under pressure .
Generally , confast screws with high tensiles strength for drill block or concrete objects . dacromet finish on surface is perfect for resistance of corrosion .
