What must be used to drill a hole in the masonry when installing a masonry fastener?
The 3/16” diameter masonry screw requires the use of 5/32” carbide tipped bit for drilling the hole. The 1/4” diameter requires the use of a 3/16” carbide tipped bit.
How much deeper than the anchor being installed should the hole be drilled?
How to drill hole: When drilling a hole into concrete, brick or block base material, the hole must be drilled 1/2″ deeper than the concrete anchor will penetrate. Why: The extra depth of the hole will ensure that the anchor does not bottom out and will allow space for dust from the drilling process.
What information is most important when determining which fastener to use?
