Cross Recess Flat Head Hi low Threads Confast Screws Square Cone Point for Concrete
Product Description
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 .
