JLHY Self-Tapping Screws

Features

Self-Tapping screws features include a sharp, hardened tip that can cut its own thread into materials such as wood, plastic, and metal, eliminating the need for pre-drilling. They come in various head styles, including flat, round, and pan heads, to suit different applications. The screw's design allows for quick and easy installation, reducing assembly time. Moreover, self-tapping screws provide a secure hold, thanks to their deep and coarse threads, which increase resistance to pull-out and stripping. Available in a range of sizes and finishes, these versatile fasteners are suitable for both indoor and outdoor projects, making them a popular choice for DIY enthusiasts and professionals alike.

Applications

Self tapping screws are widely used in various applications due to their ability to tap and thread their own holes as they are driven into materials. They are commonly found in the construction industry for attaching wood to metal, or in HVAC systems for fastening thin metal sheets. In automotive manufacturing, self-tapping screws secure components such as door panels and bumpers. Additionally, these screws are utilized in furniture assembly, where they can easily join particle boards and MDF (Medium Density Fiberboard) without the need for pre-drilling. Their versatility also makes them suitable for DIY projects, electronics, and even in the aerospace sector for non-structural assemblies.

Technology & OEM

Material: 

Stainless or zinc-plated steel, which offer varying degrees of corrosion resistance, are alternatives to case-hardened carbon steel, which is typically used.Carbon Steel: Common, often zinc-plated for indoor use.

410 Stainless Steel: Strong enough to drill through hard material and offers good corrosion resistance.

18-8 or 316 Stainless Steel: Superior corrosion resistance, typically used for exterior applications.

Common surface treatments such as Dacromet, phosphating, blackening, soap phosphating, and galvanizing.
