Captive screws, also known as captive panel screws or captive fasteners, feature a permanently attached washer or retainer that prevents the screw from becoming lost or misplaced. They are commonly used in equipment enclosures, access panels, and electronic devices where frequent maintenance or servicing is required. Shoulder screws, also known as shoulder bolts or stripper bolts, feature a cylindrical shoulder between the head and the threads. They are used in applications requiring precise alignment or spacing, such as machinery, automotive components, and tooling fixtures. Shoulder screws may have hex, socket, or slotted heads and are available with various shoulder diameters and lengths.
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.
Passivation (for Stainless Steel Screws) – Passivation is a surface treatment specifically designed for best stainless steel screws. It enhances the corrosion resistance of stainless steel by removing free iron from the surface and creating a protective oxide layer. This process results in a smooth, clean, and shiny appearance and improves the overall durability of the screws. Recommendation for Clients: Passivated stainless steel screws are perfect for industries requiring high strength and corrosion resistance, such as in the medical or aerospace sectors. For clients looking for both function and appearance, this treatment is highly recommended. Discover more information on 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.
Automotive Industry (240–500 Hours): Automotive fasteners used in automobiles, particularly in parts exposed to weather, moisture, and road salt, require 240 to 500-hour salt spray tests. These fasteners are often coated with protective layers, such as zinc plating, to prevent corrosion and maintain their integrity. Corrosion resistance is crucial for automotive safety components, such as suspension bolts, brake systems, and body parts. Aerospace Industry (500–1000 Hours): Aerospace fasteners, which are used in aircraft, helicopters, and spacecraft, are subject to harsh conditions, including high altitudes, humidity, and temperature extremes. As such, these fasteners typically undergo 500 to 1000-hour salt spray tests to ensure their reliability in demanding environments. Aerospace fasteners are often made of high-strength alloys and are coated with special corrosion-resistant materials to ensure their performance over extended periods.
