Non-detaching screws can be riveted onto iron plates, allowing free screwing in and out. The entire assembly remains securely embedded in the panel without detaching, hence also called non-falling screws. The outer hand-twist sleeve is typically embossed with straight knurls for easy hand-tightening or manual fastening, so it is also referred to as hand-tight screws or hand-twist screws.Non-detaching panel screws (spring screws) can be used for installing PCB boards, occupying minimal space. The hand-tight screw's press-rivet sleeve features knurled teeth, pressed into the chassis or thin sheet holes (note: the drilled hole diameter of the thin sheet must meet specific requirements relative to the press-tooth diameter of the spring screw), forming an exposed spring screw that is hand-twisted at the other end (i.e., the hand-twist end). Due to the internal fixed spring, the screw moves in and out relative to the other end of the thin sheet. This solution addresses the challenge of frequently needing to remove screws and is very convenient and practical.Name: Non-detaching screw, panel screw, spring hand-tight screwMaterial: Combination of carbon steel screw, carbon steel press-rivet sleeve, and aluminum hand-twist sleeve; combination of stainless steel screw, stainless steel press-rivet sleeve, and aluminum hand-twist sleeve. The non-detaching panel screws produced by Yaoda Hardware*** are entirely manufactured and assembled in-house, except for the spring, which is outsourced, with strict quality control.The panel spring screw (non-detaching screw) consists of several components:1. Screw part (used to fasten the other end of the chassis thin sheet; typically made of carbon steel or stainless steel, with cross or slotted head for tool tightening)2. Hand-twist sleeve (usually knurled with straight patterns, typically made of aluminum, sometimes anodized black as needed)3. Press-rivet sleeve (used for riveting onto the panel)4. Spring (facilitates the extension and retraction of the screw and prevents the entire assembly from detaching)After each component is produced, they are assembled into one unit, and the hand-twist part is pressed to fit together with the press-rivet part via the spring, forming a complete non-detaching spring panel screw.PF21 Type PF22 Type Press-in Style Panel Fastener   Assemblies PF21 PF22PF21-M3-12.3PF21-M3-14PF21-M3-15.5PF21-M3-17.1PF21-M3.5-16.4PF21-M3.5-18PF21-M3.5-19.6PF21-M3.5-21.2PF21-M4-16.9PF21-M4-18.5PF21-M4-20PF21-M4-21.6PF21-M5-16.9PF21-M5-18.5PF21-M5-20PF21-M5-21.6PF21-M6-20.5PF21-M6-22.1PF21-M6-23.7PF21-M6-25.3PF21-440-12.3PF21-440-14PF21-440-15.5PF21-440-17.1PF21-632-16.4PF21-632-18PF21-632-19.6PF21-632-21.2PF21-832-16.9PF21-832-18.5PF21-832-20PF21-832-21.6PF21-032-16.9PF21-032-18.5PF21-032-20PF21-032-21.6PF22-M3.5-16.4PF22-M3.5-18PF22-M4-20PF22-M3.5-21.2PF22-M4-16.9PF22-M4-18.5PF22-M5-20PF22-M4-21.6PF22-M5-16.9PF22-M5-18.5PF22-M6-23.7PF22-M5-21.6PF22-M6-20.5PF22-M6-22.1PF22-440-15.5PF22-M6-25.3PF22-440-12.3PF22-440-14PF22-632-19.6PF22-440-17.1PF22-632-16.4PF22-632-18PF22-832-20PF22-632-21.2PF22-832-16.9PF22-832-18.5PF22-032-20PF22-832-21.6PF22-032-16.9PF22-032-18.5PF22-0420-23.7PF22-032-21.6PF22-0420-20.5PF22-0420-22.1PF22-0420-25.3<img src="https://img2.fr-trading.com/0/5_1012_2108556_750_750.jpg.webp"/> more>

Product Description:PEM nuts, also known as rivet nuts or self-clinching nuts, are a type of nut used on thin sheets or metal plates. They are circular in shape, with one end featuring knurled teeth and a guide groove. The principle involves pressing the knurled teeth into a pre-set hole in the metal plate. Generally, the diameter of the pre-set hole is slightly smaller than the knurled teeth of the PEM nut. Under pressure, the teeth are forced into the plate, causing plastic deformation around the pre-set hole. The deformed material is squeezed into the guide groove, resulting in a locking effect.PEM nuts are categorized by material into free-cutting steel PEM nuts (S type), stainless steel PEM nuts (CLS type), stainless iron PEM nuts (SP type), and copper/aluminum PEM nuts (CLA type), each suited for different environmental conditions. Specifications typically range from M2 to M12. There is no unified national standard for PEM nuts, and they are commonly used in chassis, cabinets, and sheet metal industries.Nut specifications: S-256-0 S-256-1 S-256-2 S-348-0 S-348-1 S-348-2 S-440-0 S-440-1 S-440-2 S-440-3 S-632-0 S-632-1 S-632-2 S-632-3 S-832-0 S-832-1 S-832-2 S-832-3 SS-024-0 SS-024-1 SS-024-2 SS-024-3 SS-032-0 SS-032-1 SS-032-2 SS-032-3 S-1224-1 S-1224-2 S-1224-3 S-0420-0 S-0420-1 S-0420-2 S-0420-3 S-0428-1 S-0428-2 S-0428-3 S-0518-1 S-0518-2 S-0518-3 S-0524-1 S-0524-2 S-0524-3 S-0616-1 S-0616-2 S-0616-3 S-0624-1 S-0624-2 S-0624-3 S-0813-1 S-0813-2 S-0820-1 S-0820-2 CLS-256-0 CLS-256-1 CLS-256-2 CLS-348-0 CLS-348-1 CLS-348-2 CLS-440-0 CLS-440-1 CLS-440-2 CLS-440-3 CLS-632-0 CLS-632-1 CLS-632-2 CLS-632-3 CLS-832-0 CLS-832-1 CLS-832-2 CLS-832-3 CLSS-024-0 CLSS-024-1 CLSS-024-2 CLSS-024-3 CLSS-032-0 CLSS-032-1 CLSS-032-2 CLS-1224-1 CLS-1224-2 CLS-1224-3 CLS-0420-0 CLS-0420-1 CLS-0420-2 CLS-0420-3 CLS-0428-1 CLS-0428-2 CLS-0428-3 CLS-0518-1 CLS-0518-2 CLS-0518-3 CLS-0524-1 CLS-0524-2 CLS-0524-3 CLS-0616-1 CLS-0616-2 CLS-0616-3 CLS-0624-1 CLS-0624-2 CLS-0624-3 CLS-0813-1 CLS-0813-2 CLS-0820-1 CLS-0820-2 S-M2-0 S-M2-1 S-M2-2 S-M2.5-0 S-M2.5-1 S-M2.5-2 S-M3-0 S-M3-1 S-M3-2 S-M3.5-0 S-M3.5-1 S-M3.5-2 S-M4-1 S-M4-1 S-M4-2 SS-M5-0 S-M5-1 SS-M5-2 S-M6-0 S-M6-1 S-M6-2 S-M8-1 S-M8-2 CLS-M2-0 CLS-M2-1 CLS-M2-2 CLS-M2.5-0 CLS-M2.5-1 CLS-M2.5-2 CLS-M3-0 CLS-M3-1 CLS-M3-2 CLS-M3.5-0 CLS-M3.5-1 CLS-M3.5-2 CLS-M4-1 CLS-M4-1 CLS-M4-2 CLSS-M5-0 CLSS-M5-1 CLSS-M5-2 CLS-M6-0 CLS-M6-1 CLS-M6-2 CLS-M8-1 CLS-M8-2.Installation:Application Technical Guide:1.

Product Description:Vacuum Cleaner Canister Vacuum Cleaner Box Wire High-Frequency Induction Welding MachineWorking Principle:The wire high-frequency induction welding machine primarily uses induction heating (non-contact) for metals, enabling rapid heating with advantages such as energy savings, compact size, ease of operation, convenient and reliable installation, and fast heating speed.The wire high-frequency induction welding machine is equipment for welding thermoplastics, such as vacuum cleaner canisters, vacuum cleaner boxes, and vacuum cleaner end caps. It is specifically designed for forming plastic parts with special structures and for preheating and embedding metal and plastic parts for welding, offering safety, reliability, and ease of operation. It is suitable for welding automotive parts, oversized plastic components, household appliances, optoelectronic products, and embedded applications. The high-frequency induction power ranges from 15KW to 25KW, making it applicable for materials like PP, PC, ABS nylon, thermoplastics, and glass fiber-reinforced plastics.Due to the large size and complex structural design of products like vacuum cleaner canisters and boxes, which require airtight and watertight welding, conventional ultrasonic welding technology is limited by product dimensions, while techniques like hot plate welding are constrained by structural design and welding requirements. Additionally, these methods often have slow welding cycles, failing to meet expected production volumes. The wire high-frequency induction welding machine effectively addresses issues related to product size and structural challenges, while also increasing welding output to meet production requirements. more>
