At JM Hardware®, we specialize in manufacturing high-quality speed nuts, designed to meet the diverse requirements of industries such as automotive, electronics, appliances, and construction. Our speed nuts are available in a wide variety of materials, finishes, grades, and standards, making them ideal for numerous applications. Below, we provide a detailed overview of our speed nut offerings, covering different names, materials, surface treatments, grades, standards, applications, testing methods, and production processes.

Flat round washers are flat and smooth and are primarily used with bolts and nuts to provide a larger bearing surface, which distributes the load evenly over the surface area, so it isn’t damaged. They are also used to ensure that the nut is pressed against a smooth surface, which reduces the chance that it will gradually loosen.Flat Washers are circular with a center hole, are most commonly used to meet a broad range of fastening applications. They increase a nut or fastener's head bearing surface, spreading the clamping force over a bigger area. They are useful when materials are oversized, soft, or have irregular shaped holes.

Pocket hole screws are specialized fasteners designed to create strong, reliable joints in woodworking projects. These screws feature a self-tapping design, allowing them to cut through wood effortlessly without the need for pre-drilling. At JM Hardware®, a leading screw manufacturer, we produce high-quality pocket hole screws tailored for various applications, ensuring durability and performance.Our pocket hole screws are available in multiple materials, including carbon steel, stainless steel, and alloy steel, offering excellent strength and corrosion resistance. With a variety of finishes, such as zinc plating, black oxide, and phosphate coatings, they are suitable for indoor and outdoor woodworking projects. Additionally, their coarse threads are perfect for softwoods, while fine threads provide superior grip in hardwoods.As a trusted screw manufacturer, we ensure our pocket hole screws meet the highest industry standards, making them ideal for furniture assembly, cabinetry, and other woodworking tasks. Choose JM Hardware® for precision-engineered pocket hole screws that deliver exceptional results in your projects.

Split lock washers, also known as spring lock washers,  are designed with a split at one point and bent into a helical shape. This causes the washer to exert a spring force between the fastener’s head and the substrate, creating more friction and resistance to rotation.Lock washers are specially designed to keep threaded fasteners from loosening. They prevent vibrations and some have external teeth to prevent rotation. These washers are often found in airplanes and in structural applications.
