Types of M12x1.5 Bolts
Hex Bolts
Hex bolts are the most common type of M12x1.5 bolts. They feature a hexagonal head designed for use with a wrench. These bolts are suitable for various applications, including machinery assembly and structural support. Available in different grades, they can offer varying strength levels, making them versatile for both light and heavy-duty tasks. Leading suppliers like Bolt Depot provide an extensive range of hex bolts.
Flange Bolts
Flange bolts have an integrated flange that acts as a washer, distributing the load over a larger surface area. This design reduces the risk of damage to the material being fastened and is particularly useful in automotive applications, such as wheel mounting. For instance, sites like Summit Racing offer M12x1.5 flange bolts tailored for high-performance vehicles.
Set Screws
Set screws, or grub screws, are typically used to secure one part to another without the need for a nut. They are often found in machinery where components need to be locked in place. Their design allows for various head types, depending on the application. You can find a variety of set screws at vendors such as Grainger.
Lug Bolts
M12x1.5 lug bolts are specifically designed for securing wheels to vehicles. They must meet specific standards for strength and durability to withstand the forces encountered during driving. Many automotive supply stores, like O’Reilly Auto Parts, stock these essential components for both cars and trucks.
Stainless Steel Bolts
These bolts are made from stainless steel, providing excellent resistance to corrosion, making them ideal for outdoor and marine applications. Their durability ensures a long service life, even in challenging environments. You can explore options for stainless steel M12x1.5 bolts on sites like BelMetric.
