Studs are externally threaded fasteners that typically look like and operate as threaded bars. They’re different from screws and bolts in the fact that they don’t usually have a head that requires tightening — just continuous threading that can be paired with nuts
The D-Bolt is a rock bolt that is specially designed to absorb energy through elongation of the bolt material. The standard version of the bolt is a smooth steel bar with a number of anchors along its length. The sections between anchors are approximately 1 m long
an axle supporting only one wheel and carried at the other end on the vehicle frame or some other support
Shoulder bolts are used in in a variety of ways and for various purposes. Their two primary functions in injection molds are limiting the distance a plate travels and pulling a plate during mold opening. Shoulder bolts are frequently used in three-plate molds and stripper-plate molds
Pan Head bolts are slightly rounded head with short vertical sides. The round head bolts are similar to carriage bolts, with the exception that there is no square neck under the head
If the vehicle has studs coming out of the hub, you will use a nut to fasten the wheel to the vehicle. Vehicles without studs will use a bolt to fasten the alloy wheel to the hub of the vehicle. Bolts and nuts have various diameter heads, hex sizes, thread sizes and seatings
A drain plug is a plug which is taken out to allow a fluid to be drained from a tank such as an engine oil pan or sump. Remove the oil drain plugand allow oil to drain out. Remove the drain plug under the engine with the wrench, and let the oil flow into the pan
It is typically used to connect a fluid line to a rigid, internally threaded hydraulic component. The bolt is assembled through the center of the union, usually with face seals on either side of the union, to create a fluid path between the external ports on the union and bolt
Con rod bolts are critical fasteners used for tightening con rod caps, and they connect the con rod to the crankshaft. They are normally tightened to torque + angle, have external driver heads, and no washer. There are different types of con rod bolts, for example, unloaded or ground
Cylinder-head bolts are the connecting elements between engine block, cylinder-head gasket, and cylinder head. The bolt tightening force is an important factor for the mutual sealing of combustion chamber, lubricant and coolant channels, and the ambient air
