Combined with our cutting, grinding, lapping and polishing capabilities, our machining centers enable us to offer vertically integrated solutions that shorten production times for difficult to machine small diameter machining parts.
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.
To help our clients achieve the best results at the most affordable price, we recommend using zinc plating or black oxide for standard applications. These options provide a balance between cost, appearance, and durability. For clients looking for more specific finishes or higher-end performance, treatments like anodizing or powder coating may be worth considering. Ultimately, the choice of surface treatment depends on the client’s specific needs, the product application, and the desired aesthetic. At JM Hardware, a professional custom screw manufacturer, we are committed to providing high-quality surface treatments for screws and fasteners, ensuring that our clients receive the best combination of aesthetics, performance, and cost-efficiency.
Anchors: Securing Objects To Concrete And Masonry – Anchors are specialized fasteners designed to secure objects to concrete, brick, and other masonry materials. Unlike screws, which rely on threads for holding power, anchors use a variety of mechanisms to create a secure hold in solid materials. They are essential for applications where traditional fasteners, like screws and nails, would be ineffective. Types of Anchors: Anchors come in a wide variety of types, each optimized for specific applications and base materials. Some common types include: Mechanical anchors: These anchors use expansion mechanisms to create a tight grip within the base material. Examples include wedge anchors, sleeve anchors, and screw anchors. Find more information on https://www.jm-fastener.com/.
In construction, bolts are often preferred for structural connections. Steel beams, columns, and trusses are typically joined using bolts to ensure a secure and stable framework. The high load-bearing capacity and ease of disassembly make bolts ideal for temporary structures, such as scaffolding, as well as permanent installations. Automotive Industry: The automotive industry relies heavily on bolts for assembling engines, transmissions, suspensions, and other critical components. The ability to withstand high loads and vibrations ensures the reliability and safety of vehicles. Bolts also allow for easy maintenance and replacement of parts, which is essential for vehicle longevity and performance.
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.
