Shoulder bolts can be used to hold various things. An excellent example is calluses on your fingers when you finger-pick the guitar or a hard brace or bandage around your shoulder from a shoulder injury. This isn't a post about that, though. These are shoulder bolts for cars. These will hold your car's frame together and keep its body glued together. If you're like most of us and have lots of weight in the rear of your vehicle, you probably need more of these to help support it all.
There are several types of shoulder bolts, with the most common being metric shoulder bolts, imperial shoulder bolts, and M6 shoulder bolts.
Metric Shoulder Bolts: Metric shoulder bolts are used in machinery and other applications requiring high strength. They are available in a wide range of materials, including carbon steel, stainless steel, and cold-drawn steel. Metric shoulder bolts have a full thread length, allowing higher torque to be applied during installation.
Imperial Shoulder Bolts: Imperial shoulder bolts are also known as imperial studs or imperial nuts, depending on which side of the pond you are on. Imperial shoulder bolts are used widely throughout the industry for easy installation and removal characteristics.
M6 Shoulder Bolt: This type of bolt is a popular choice for mounting parts or components together due to its strength and durability. The M6 shoulder bolt has a 6mm diameter shaft with an internal thread pitch of 1.00mm x 0.75mm. The head size measures 4mm in diameter across the flats
M8 Shoulder Bolt: This type of bolt is commonly used in applications that require more holding power than smaller bolts can provide. The M8 shoulder bolt has a larger diameter than standard M6 bolts at 8mm and also has a larger head size at 5mm across the flats. It has an internal thread pitch of 1.25mm x 0.75mm
Headless Shoulder Bolts: Headless shoulder bolts are used when there is not enough room for a head on the fastener. A headless shoulder bolt has a flat end instead of a traditional hexagonal head like other types of bolts. This makes them ideal for use in tight spaces where regular shoulder bolts would not fit properly.
Standard Shoulder Bolts: Standard shoulder bolts have a hexagonal head on one end and no head on the other end. These fasteners are used to secure two pieces together by driving them into one piece with a hammer or mallet before installing the second piece onto them.[MW1]
Benefits of Shoulder Bolts
There are many benefits associated with using shoulder bolts:
They're inexpensive compared to other fasteners, such as screws or rivets. This makes them an attractive option for homeowners who wa
