2011 4 22 nbsp 0183 32 The reason for the minimum set back from the plate edge is so wind or seismic forces dont pull the plate thru the anchorage Further spacing of the anchor bolts is 6 after that but since most sill plates are not 40 long the plate edge needs to be adhered to they will try to act independently Minimum 2 bolts per plate 2019 11 20 nbsp 0183 32 Table of conTenTs PRI n T e D oc T obe R 2019 www powers com au 1 ANCHORING amp FASTENING SYSTEMS Technical Manual for the Design Professional TABLE OF CONTENTS BLUE TIP 2 SCREW BOLTS ™ amp HANGERMATE ROD HANGERS ETA OPTION 1 2 Ordering Information ETA Option 1 12 BLUE TIP 2 SCREW BOLTS™ amp

In addition to embedded depth the minimum diameter required for anchor bolts is 1 2 inch 12 7 mm per the International Building Code IBC As with maximum spacing this is a minimum requirement Increasing the diameter to 5 8 inches is usually a good way to allow for some margin of error particularly in seismic regions Excluding anchors placed in mortar bed joints a minimum clearance of 188 in 6 4 mm and 189 in 12 7 mm is required between the anchor bolt and the nearest surface of masonry for fine grout and coarse grout respectively

Answer 1 of 4 There is no maximum spacing for anchor bolts In general the further away they are the better The purpose of the bolts is to prevent the column from moving In most cases the design strength of the anchor bolt connection is 10 8 2006 nbsp 0183 32 Bricks Masonry Cinder Block Paving amp Walking Stones Asphalt and Concrete How many anchor bolts are needed spacing Im building a shop 30x50 I was thinking that I need at least 1 anchor bolt for each 8 of wall section But Im reading they should go every 16 or every 48 so Im confused At every 48
