Socket Head/Allen Bolt is a bolt with a hexagonal socket in its head that is designed to be used with an Allen wrench. The Allen bolt is integral to the crank and remains in it when the crank is removed from the spindle. The primary advantage of Allen bolts is that they are perfect if you have a bolt thatâ??s down inside a narrow opening. You can stick the Allen key down into the hole and do up the bolt. A socket cap screws are machine screws with a cylindrical barrel-shaped head containing a hexagonal socket. The head has a smaller diameter than most other machine screw heads, typically just 1.5 times the nominal thread diameter. Socket cap screws may also be referred to as a socket head cap screw, a cap head socket screw, or a hex socket head screw.
A Square Head Bolts are low or medium carbon steel, externally threaded bolt, 1/4" diameter or larger, with a trimmed square shaped external wrenching head. Square head bolts were the industry standard prior to hex bolts taking over. A square head bolt has a distinctly shaped head that makes it ideal for working in blind areas. Square head bolts are now normally used in rustic look applications. With the proper tools, tightening a square head bolt is easy even when the fastener is out of your line of vision. The head design of square head bolts enables an easier wrench grip for nut tightening. They are usually used in new construction to mimic an older aesthetic or in railway applications. Square head bolt design enables an easier wrench grip for nut tightening. They are usually used in new construction along with square plate washers and taper washers. These Bolts worked really well in the railroad industry, where supervisors could check that all bolts were on based on whether the head lined up with the tie. It is common in the railroad industry, on electrical panels, and in furniture manufacturing.
