Here is an introduction to the process of how screws are made at Mochizuki Spiral Co., Ltd. First, the sales department issues a manufacturing instruction based on the orders received from customers and requests production from the manufacturing department. After that, the process involves material selection, head production (forging), and then the production of the screw body. To enhance the screw-in capability of screws like tapping screws, cuts are made at the tip of the screw according to user instructions, followed by a cleaning process. The cleaned screws undergo a final inspection to ensure they are manufactured according to JIS standards, followed by sorting and packaging before shipment. 【Process of Screw Production】 1. Screw production request 2. Material selection 3. Head production (forging) 4. Screw body production (rolling) 5. Tip cutting production (splitting) 6. Cleaning 7. Final inspection 8. Sorting 9. Packaging 10. Shipment *For more details, please refer to the PDF document or feel free to contact us.

The "Long Screw" is a roofing tile screw that can prevent head snapping and screw bending. In recent years, the diversification of residential design has led to an increased demand for longer screws. However, as the overall length increases, there is a concern that strong loads during fastening may lead to head snapping and screw bending, resulting in reduced fastening capability. This product prevents head snapping and screw bending by applying a knurling process to the body of the screw, which allows for expected cold working hardening (the material heats up and hardens when pressure is applied instantly). 【Features】 - The knurling on the body prevents head snapping and screw bending. - The split end processing at the tip improves grip and enhances workability. - The undercut below the neck ensures tight contact with the sealing packing, preventing water leakage. - Split end processing can be applied to screws up to 115 millimeters in length. *For more details, please refer to the PDF document or feel free to contact us.

The "frame adjustment screw" is an adjustment screw that can dramatically reduce the time required to correct distortions that occur when installing closet frames and door frames onto the structure. By making the ring part a cat's paw shape, the screw does not come out during adjustment, allowing only the frame to move. Additionally, by making the tip two-pronged, it suppresses the initial driving force, allowing for fastening without damaging the counterpart, and by making the screw thread sharp (approximately 30 degrees), it enables tightening with low torque (tapping screws are 60 degrees). 【Adjustment Method】 ■ Insert the adjustment screw into the frame up to the base and screw it in. ■ When the adjustment screw is turned in reverse, only the frame moves. ■ Check the vertical alignment of the frame and screw in the fixing screw to complete. *For more details, please refer to the PDF document or feel free to contact us.

The "Yachiban Screw" is a screw that can prevent 100% of water leaks. When installing solar panels on residential roofs, screws are used, but there is a concern that rainwater may enter through the gaps in the screws, leading to leaks. This product incorporates a waterproof packing to prevent rainwater intrusion. By wrapping butyl tape around the screw, it provides a double waterproofing effect. Furthermore, as a secondary benefit, it can significantly improve workability. If you have any concerns, please feel free to contact us. 【Features】 ■ Prevents water leaks ■ Improves workability *For more details, please refer to the PDF materials or feel free to contact us.

The "trapezoidal screw" is a product that can dramatically improve the pull-out strength when fixing products to hard materials such as concrete. By making the screw thread trapezoidal, the apex of the thread becomes flat, which prevents it from cutting through the resin plug and allows for greater expansion. Furthermore, the increased contact area between the screw and the resin plug enhances the pull-out strength by approximately 1.5 times compared to standard screws (tapping screws). 【Features】 ■ It does not cut through the resin plug, allowing for greater expansion. ■ The larger contact area between the screw and the resin plug allows for even stronger retention. *For more details, please refer to the PDF document or feel free to contact us.

The "PC" is a resin screw recommended for fragile, soft materials. This product features a screw thread angle of 40 degrees and a sharp angle (Type B 60 degrees), with a thread height that is 1.8 times higher than that of tapping screws, making it less likely to crack the resin. Additionally, the return torque is improved by approximately 1.5 times compared to standard Type B tapping screws. It can also be tightened with about 3/4 of the force. If you are having trouble with resin screws, please feel free to contact us. 【Features】 ■ Shape that is less likely to crack resin ■ Resistant to loosening ■ Reduced tightening torque *For more details, please refer to the PDF document or feel free to contact us.

"VBA" is a screw designed with a screw shape that works well with hard hardwoods, including dense hardwoods. Recently, the use of lattice and other hardwoods has been increasing, but hardwoods are tough, and standard wood screws and tapping screws are not recommended due to poor workability. This product has a shape that allows for easy entry into hard wood, and it can be tightened with about two-thirds the force compared to wood screws. Furthermore, it offers a 30% improvement in pull-out strength compared to wood screws. If you are having trouble driving screws into hard wood, please do not hesitate to contact us. 【Features】 ■ Shape that easily penetrates hard wood ■ Reduced tightening torque ■ Improved pull-out strength *For more details, please refer to the PDF document or feel free to contact us.
