RAMSET 721 Operations Instructions download pdf (Page 8)

FASTENING APPLICATIONS

Your Ramset tool can be used for a wide

range of fastening needs in a variety of

base materials. Reading and follow these

important fastening guidelines will help you

get the best results from your tool, fasteners,

and powder loads, as well as help you

perform these fastening operations safely

and effectively.

Powder actuated fastenings are permanent

fastening so attempting to remove a fastener

from concrete or steel may result in serious

injury.

Fastening to Concrete

When fastening into concrete, always maintain

a minimum spacing of 3” between fastenings

and 3” from any free edge. Concrete thickness

should be at least three times the intended

penetration depth into the concrete. The

primary exception to the 3” edge distance

can occur in a sill plate application where,

by necessity, the edge distance is reduced.

Driving fasteners too close to an edge or too

close to each other can cause the concrete

edge to fail or fasteners to fly free.

Fastening to Concrete Block

or to Masonry Walls

While this application is not recommended,

when used, it is necessary to take care to

observe a 3” edge distance to avoid cracking

the block and over penetration of the fastener

to avoid loss of holding value. Fastening

may be made into the horizontal joint but

not into the vertical joint.

Fastening to Steel

Your Ramset tool can be used for fastening

on the flat surfaces of structural steel.

When fastening into steel, always maintain

a minimum spacing of 1-1/2” between

fastenings and 1/2” from any edge.
