Custom screws supplier in China: JM Hardware is a custom bolt manufacturer with 18 years experiences, our bolts are used by a broad range of industries requiring assemblies and fastening applications. These threaded fasteners can connect machine parts, mount equipment, and more. As a removable fastener, they also facilitate the regular maintenance and inspections that keep equipment running longer. JM offers both standard and custom bolts and fasteners to meet different grades and specifications. This ensures we can cover the full spectrum of our manufacturing customers’ applications, including Mining, Heavy equipment, Construction, Transportation, Automotive and Energy and alternative energy.

As a leading screw manufacturer, we offer screws in a variety of materials, including carbon steel, stainless steel, alloy steel, and even non-metallic options. Our screws are available in multiple finishes, such as zinc plating, hot-dip galvanizing, black oxide, and Teflon coatings, to ensure durability and resistance to environmental factors. Wood Screws: Perfect for carpentry and furniture projects, offering strong and secure connections in wood materials. Self-Drilling Screws: Commonly used in construction and metalworking, featuring a drill bit tip for easy installation in metal sheets. Drywall Screws: Designed specifically for fastening drywall panels to wood or metal frames with high pull-out strength.
Validation of Surface Coatings: Salt spray tests help validate the effectiveness of surface treatments such as galvanization, plating, or coatings. Fasteners with longer corrosion resistance typically have higher-quality coatings or specialized treatments that protect against rust. A longer test duration confirms the durability of these treatments. Cost-Effective in the Long Run: Although salt spray testing can be time-consuming and costly, a longer test duration ultimately ensures that the fasteners will last longer in real-world conditions. This reduces the risk of failures after installation, saving costs related to replacements, repairs, and warranty claims.
Cost-Effective Solutions for Clients – For clients looking to keep costs low while still achieving an aesthetically pleasing finish, we recommend focusing on the following surface treatments: Zinc Plating: As one of the most affordable options, zinc plating is ideal for achieving a shiny, metallic finish. It’s suitable for automotive, consumer electronics, and general industrial applications where basic corrosion resistance is required. Black Oxide: This treatment is relatively low-cost and gives screws a sleek, black finish. It’s perfect for applications where a non-reflective, matte finish is preferred, such as automotive interiors and certain electronics.
Construction: They are used to distribute the load of bolts in structural steel connections and timber framing. Automotive: Washers are crucial for preventing damage to car body panels and ensuring proper tightening of fasteners. Plumbing: They are used with nuts and bolts to create leak-proof connections in pipes and fixtures. Electrical: Washers provide insulation and prevent loosening of screws in electrical components and appliances. Always use washers with nuts and bolts to prevent damage to the underlying material and ensure a secure connection. Choose the appropriate washer type based on the specific application and the type of fastener being used. Find even more details at https://www.jm-fastener.com/.
Uniform Load Distribution: The use of a washer with a bolt helps to distribute the load evenly across the surface of the material. This uniform distribution reduces the stress concentration at any single point, preventing damage and extending the lifespan of the assembly. In contrast, screws can create high-stress points that may lead to material fatigue and failure over time. Versatility in Materials and Sizes: Bolts are available in a wide range of materials and sizes, making them suitable for diverse applications. They can be made from steel, stainless steel, brass, titanium, and other materials, each offering specific benefits such as corrosion resistance, high strength, or lightweight properties. The availability of different sizes allows for precise matching with the requirements of the application.
Lag screws, also known as lag bolts, are heavy-duty fasteners used for securing heavy objects to wood or other materials. They feature coarse threads and a hexagonal head, allowing for high-strength fastening. Lag screws are commonly used in construction, framing, and woodworking applications. Concrete Screws: Concrete screws, also known as masonry screws or Tapcons, are specifically designed for fastening objects to concrete, brick, or block. They feature special threads and a hardened steel construction for secure anchoring in masonry materials. Concrete screws may require pre-drilling or use of a hammer drill for installation. Drywall Screws: Drywall screws are designed for fastening drywall to wood or metal studs. They feature coarse threads, a sharp point, and a bugle head with a Phillips or square drive for easy installation. Drywall screws may have fine threads for metal studs or coarse threads for wood studs.
