Ordinary bolts are generally 4.4, 4.8, 5.6 and 8.8. High-strength bolts are generally 8.8 and 10.9, of which 10.9 is the majority. Many screws use screwdriver bit fittings instead of external wrenches. The screwdriver should be in line with the fastener and not applied from the side. They are smaller than most wrench heads and usually cannot apply the same torque. It is sometimes assumed that the head of the screwdriver implies a screw, and the wrench implies a bolt, although this is incorrect. Coach screws are large square head screws with tapered wood screws, used to fix iron products to wood.
The overlapping head design is the Allenor Torx head; hexagonal or spline socket. These modern designs cover a large size range and can carry considerable torque.
High-strength bolt connection has the advantages of simple construction, good mechanical performance, detachability, fatigue resistance, and no loosening under dynamic load, and is a promising connection method.
