The Roof Washer is a specialized washer used for fastening roofing panels (such as corrugated sheets or skylight panels). Its core function is to provide waterproof sealing. It is typically made of weather-resistant rubber or EPDM combined with a metal backing. When the screw is tightened, the washer compresses, tightly filling the gap between the screw and the roofing material, effectively preventing rainwater ingress and ensuring the long-term dryness and integrity of the roof structure.
The installation of a Breakaway Screw is very simple: it only requires a standard driving tool (like a hex wrench or screwdriver) for tightening. Once the torque reaches the designed value, the head automatically breaks off, signaling installation completion and simultaneously activating the anti-theft function. This feature of simultaneous installation and theft-prevention avoids the hassle of specialized tools, ensuring fast, efficient, and secure permanent fastening on the production line.
This nut is typically designed with a Hex Socket drive recess, allowing a wrench to securely screw the nut into the external threaded hole. The advantage of the hex socket drive is its ability to transmit high torque without the tool requiring external clearance, making it ideal for recessed mounting or compact designs. It ensures the nut is precisely positioned and securely locked into the base, providing a solid foundation for the subsequent internal threaded connection.
Another major advantage of the Drive Pin Rivet is its extremely low tool requirement. Installation can be completed using only a standard hammer or a light pneumatic impact tool; no specialized riveting tool is needed. This significantly reduces equipment procurement and maintenance costs, and makes on-site repairs and emergency installations highly convenient. It offers a cost-effective option for applications requiring an economical and fast blind fastening solution. ★OTHER SIZE, MATERIAL ARE AVAILABLE UPON REQUEST

SMALL FLANGE BLIND RIVET NUT, OPEN END
SEM, SAM, SAI SERIES
The Large Flange Rivet Nut (SAM/SAI) features an enlarged flange design, aiming to significantly increase the contact area with the panel. This reinforced design disperses the installation stress more evenly onto the base material, thereby greatly enhancing the pull-out strength and reducing the risk of damage to soft or composite panels during tightening. The large flange provides more reliable support for the connection, making it suitable for heavy-duty applications that must withstand large axial loads or frequent disassembly.

The Jack Nut's unique expanding structure grants it an ultra-wide grip range, allowing it to reliably accommodate tolerances or variations in panel thickness. The large, four-legged bearing surface formed upon expansion tightly grips the base material, providing extremely high pull-out strength and excellent resistance to vibratory loosening due to enhanced friction. This ensures the threaded connection remains stable long-term, even in less-than-perfect installation environments. ★OTHER SIZE, MATERIAL ARE AVAILABLE UPON REQUEST
Maintaining the stability of threaded connections is crucial in high-vibration applications. The key advantage of the SERRATION UNDER HEAD SERIES is its ability to create a mechanical lock on the panel via the serrations, thereby increasing friction and fundamentally resisting loosening torque. It also maintains the convenience of unidirectional installation. This design, which combines assembly efficiency with excellent anti-loosening performance, makes it an ideal choice for durable, high-strength fastening requirements.
