JM Hardware is a custom screw manufacturer, we have Multi-station machines, these machines can produce complex geometries screw, it achieve significant cost save over traditional manufacturing. Cold head, thread roll and other professional equipment: these equipment can production M2.5-M30 size, 6-180MM length, and can customized 1000MM length screw. Custom screws come in almost every size and style imaginable, but engineers and OEMs know there are applications where an off-the-self fastener won’t suffice. Designing a custom or modified screw is a perfect solution for these situations, saving you time and money over searching for stock screws to meet your mechanical application requirements.
Construction and Heavy Equipment (240 Hours): Fasteners used in construction and heavy machinery are exposed to various environmental conditions, including moisture, dirt, and chemicals. These fasteners are usually tested for 240 hours to ensure that they remain functional and resistant to corrosion in challenging outdoor environments, such as those encountered on construction sites or in mining operations. Electronics and Medical Devices (24–48 Hours): In electronics and medical devices, fasteners are exposed to moisture, cleaning agents, and other mild corrosive conditions. For these applications, 24 to 48-hour salt spray tests are often sufficient to evaluate the durability and corrosion resistance of fasteners used in enclosures, connectors, and medical instruments.
Powder coating is a process where a dry powder is applied to the custom machine screws’surface and then cured in an oven. It results in a smooth, durable finish that can be applied in various colors. This treatment is particularly popular for screws used in automotive, home appliances, and outdoor furniture because of its high resistance to wear, weather, and UV damage. The finish can also be matte or glossy depending on the client’s preference. Recommendation for Clients: Powder coating is ideal for applications where both color and durability are important, especially in industries like automotive or outdoor products. However, it can be more expensive than other surface treatments, so it’s best suited for high-end products or when long-lasting aesthetics are crucial.
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. See a lot more information on https://www.jm-fastener.com/.
Critical Safety Applications: In applications where safety is critical, such as aerospace, automotive, and medical devices, bolts provide a more reliable and secure connection. The ability to use high-strength materials and locking mechanisms ensures that the connection remains intact under various conditions. While both bolts and screws have their place in fastening applications, bolts offer distinct advantages that make them the preferred choice for many scenarios. The higher load-bearing capacity, better clamping force, ease of disassembly and reassembly, uniform load distribution, versatility, enhanced security, and compatibility with high-strength applications make bolts superior in demanding environments.
Stainless steel bolts are highly resistant to rust and corrosion due to the presence of chromium, which forms a passive oxide layer on the surface, protecting the underlying metal from oxidation. Types of stainless steel commonly used for bolts include austenitic grades such as 18-8 (304) and 316, which offer excellent corrosion resistance in marine and harsh environments. Galvanized bolts are coated with a layer of zinc through a hot-dip galvanizing process, providing a sacrificial barrier against corrosion. The zinc coating prevents moisture and corrosive substances from reaching the underlying steel substrate, significantly extending the lifespan of the bolt.
