With a focus on customization, JM Hardware® can manufacture screws in different dimensions, threads, and head styles to suit your exact specifications. Whether you need screws for construction, automotive, electronics, or specialized projects, we are your one-stop solution for high-quality fasteners. Socket Head Cap Screws: Known for their high strength, these screws are used in mechanical and automotive applications. Deck Screws: Coated for corrosion resistance, ideal for outdoor decking and construction projects. Hex Lag Screws: Heavy-duty screws suitable for structural wood-to-wood connections. Thumb Screws: Hand-adjustable screws used in applications requiring quick assembly or disassembly.
Recommended Salt Spray Test Durations for Different Industries and Applications: Different industries and applications require varying salt spray test durations depending on the environment in which the fasteners will operate. Here are some general guidelines: Marine and Offshore Industries (1000+ Hours): Fasteners used in marine and offshore applications, such as shipbuilding, offshore oil rigs, and coastal infrastructure, are exposed to highly corrosive saltwater environments. For these applications, fasteners typically undergo 1000-hour or longer salt spray tests to ensure long-term protection against rust and corrosion. These custom machine fasteners may be coated with durable materials like zinc, nickel, or stainless steel to improve corrosion resistance.
Powder Coating: While slightly more expensive, powder coating is ideal for outdoor applications and products that require both durability and color variety. It’s a good choice for clients seeking a long-lasting, high-quality finish. The Right Surface Treatment for Your Screws – When producing custom machine screws for customers, aesthetics are crucial, and selecting the right surface treatment is essential for achieving the desired look while maintaining functionality. Depending on the client’s needs, surface treatments such as zinc plating, black oxide, anodizing, or powder coating can be used to enhance both the visual appeal and performance of the screws.
Types of Screws – A wide variety of custom made screws are available, each optimized for specific applications. Some common types include: Wood screws: These screws have a tapered shaft and a coarse thread, specifically designed for use in wood. Machine screws: Used for fastening metal components, custom machine screws have a cylindrical shaft and are available with a variety of head types, such as flat, oval, and pan heads. Self-tapping screws: These screws form their own thread as they are driven into the material, eliminating the need for a pre-tapped hole. Drywall screws: Designed for fastening drywall to studs, drywall screws have a bugle head and a coarse thread. Discover additional information at jm-fastener.com.
Tailored Designs: The design and shape of non-standard nuts can vary widely, from traditional hex nuts and flange nuts to specialized designs such as wing nuts, knurled nuts, or captive nuts, adapted to specific installation, accessibility, or aesthetic considerations. Specialized Industries: Non-standard nuts find applications in specialized industries such as aerospace, automotive, marine, electronics, and medical devices, where standard nuts may not meet the unique demands of the application. Custom Machinery: These nuts are often used in custom machinery, equipment, and tooling where off-the-shelf fasteners cannot provide the required fit, strength, or performance.
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.
