About bolts

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

Normal bolt!



When the clearance holes are not concentric thread



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!

That's all I wanted to say! Add new developments
