Screws supplier today: 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. Discover extra information on custom made bolt.
Standard fasteners mainly include bolts, studs, screws, set screws, nuts, washers and rivets. There are many structural types of bolts, and most of the heads are hexagonal. For bolts subjected to impact, vibration or variable load, in order to increase flexibility, the polished rod part is made into a thin section or hollow. The seat end of the stud is screwed into the threaded hole of the connected piece, and the nut equipped with the nut end is similar to the bolt nut. The structure of the screw is roughly the same as that of the bolt, but the head shape is diverse to adapt to different assembly space, tightening degree and connection appearance. Set screws have different head and end shapes to accommodate different tightening degrees. There are also many types of nuts, with the hexagonal shape being the most widely used.
Zinc plating involves electroplating a layer of zinc onto the surface of the bolt, providing corrosion resistance through barrier protection and sacrificial corrosion. Zinc-plated bolts are commonly used in indoor and low-corrosion environments, offering a cost-effective solution for rust prevention. Aluminum bolts are lightweight and naturally resistant to corrosion due to the formation of a protective oxide layer on the surface. They are often used in applications where weight savings and corrosion resistance are priorities, such as aerospace and marine industries. Titanium bolts offer excellent corrosion resistance, high strength-to-weight ratio, and durability in harsh environments. They are commonly used in aerospace, marine, and chemical processing applications where resistance to corrosion and high temperatures is essential.
Choosing the right anchor type and size is crucial for ensuring a secure and reliable hold. Consider the base material, the weight of the object being anchored, and the environmental conditions when selecting anchors. Blind rivets: Also known as pop rivets, these are installed from one side of the workpiece, making them ideal for applications where access to the back side is limited. Tubular rivets: These have a hollow shaft, making them lighter and easier to install than solid rivets. Chemical anchors: These anchors use a bonding adhesive to secure a threaded rod or stud into the base material. They offer high strength and are suitable for heavy-duty applications.
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.

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.
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.
