About fasteners! Will be 10 photos, please do not break ... if anyone has even its own design, please add

For holes drilled too close to the edge



It is used when the depth of the hole is unknown



For countersunk holes on the wrong side



Bolt banana



For holes with a double countersunk



Flexible bolt



PTO bolt



For non-existent holes!
