Custom Tapping and Fastening

Custom tapping is a form of chemical anchoring where cupboards, wall

hangers or other heavy cabinetry can be secured in place. However, the

bolts or screws holding heavy cantilevered items can be easily removed

facilitating the re-location of the cabinetry. Custom tapping is done by

molding the threads of bolts and screws into an adhesive plug, rather

than being mechanically anchored into lag shields. The tough molding

properties of this product allow it to form and retain a high-strength, non-

brittle interlock between holes cored into concrete, wood or masonry and

the threads of the inserted bolt or screw.

The release characteristics, upon removal, are achieved by simply spraying

the bolt or screw with 3M™ 5-Way Penetrant (or another release agent)

before the bolt or screw is inserted into the liquid 3M™ Scotch-Weld™

Urethane Adhesive DP600 Self-Leveling or DP600NS prior to its setting. To

achieve a more permanent fixture, the bolts and screws simply are not

lubricated before embedding into the liquid 3M™ Scotch-Weld™ Urethane

Adhesive DP600NS prior to curing.

Preparation For Custom-tapping:

2.

Use a round bristle brush to clean the cored holes if they have not

been freshly drilled.

3.

Use moisture-free and oil-free compressed air to blow out the debris.

4.

Lightly coat the bolts or screws with 3M™ 5-Way Penetrant.
