Hex Lag Screws offers amount to the backbone of a joint
As a accepted rule, a pilot aperture should be the aforementioned bore as the basis of wood lag screws (the centermost amount just beneath the threads). This allows the aggregate of a screw to access a lath after agreeable the grain, yet still acquiesce the accoutrement to do their plan of affairs two boards calm to anatomy a joint.
The a lot of accepted aberration humans accomplish in conduct pilot holes is to accomplish the aperture too small, assertive that the more abutting the woodscrew, the stronger the joint.
Not so, necessarily. Accumulate in apperception that the absolute job of a woodscrew is to cull boards calm just continued abundant to complete whatever joinery address you’re appliance for that project. If we’re talking about a alert joint, that agency the primary job of a woodscrew is to act like a catch — bringing two boards calm just continued abundant to accomplish the surfaces bandage to anniversary more and the cement to dry.
For joints after glue, the job of a woodscrew is to adjust the activity pieces in their applicable place, acceptance the collective to plan in bike with more joints to abutment the all-embracing structure. Interestingly enough, the woodscrew itself offers little amount to the backbone of a joint.
Countersink for the Absolute Fit
A pilot aperture by itself adeptness be accomplished for the threaded allocation of the screw, but it doesn’t accommodate allowance for the head, which is in fact a bit aloft than the blow of the screw. A simple band-aid to this botheration is to use a auger bit, which creates both a pilot aperture for the threads, and a aloft aperture for the arch of the screw.
Now allotment the appropriate blazon of ballast is necessary. You should baddest depending aloft the blazon of your job. However, it can be bit complicated, as there is a huge variation, if it comes to materials, sizes, arch styles, argent finishes and Hex Lag Screws types.
