The "Recess Inner" is a product designed to be inserted into the hole (recess) of a bolt drive, preventing the unauthorized removal of the bolt. Developed to reduce the risk of destruction and disassembly of machinery and systems, it enhances safety and can be applied without changing the conventional hex socket bolts, supporting standardization. We offer three types with different features (Barnacle, Flat, and Plain Inner), allowing you to choose an inner that suits various purposes. Additionally, we also handle the anti-tampering component "Head Spinner" for hex bolts. 【Features】 ■ Prevents accidents caused by flying chips during air blowing ■ Prevents unauthorized removal of bolts by individuals other than the administrator ■ Increases work efficiency by reducing air blowing time ■ Fits into existing hex socket bolts *For more details, please refer to the PDF document or feel free to contact us.

The Hexalobular socket, developed by the American company Textron in 1971, is a star-shaped hexagonal recess, also known as 6-lobe. The biggest feature of the Hexalobular socket is its high torque transmission efficiency, which allows for reduced tool load, miniaturization and thinning of the head, and suppression of cam-out during installation. Additionally, the Hexalobular socket was standardized as ISO 10664 in 1999 and as JIS B 1015 in 2001, contributing to the standardization of parts. This catalog features Azuma's "Hexalobular socket screws," as well as a product lineup that includes bolts, set screws, and tapping screws. [Featured Products] ■ Bolts ■ Set screws ■ Tapping screws ■ Tapping screws (for resin) ■ Tools *For more details, please refer to the PDF document or feel free to contact us.

This catalog introduces "small-headed screws" suitable for fastening in areas with limited clearance, where design aesthetics are pursued, and where weight reduction is sought. To further enhance space-saving capabilities, we also feature products that not only have a small head diameter but also a reduced head height (related: low-headed screws). These can be useful in areas where deep recessing is difficult, and the recess shapes are hexagonal (with tapping screws being cross-shaped), allowing the use of common tools. [Featured Products] - Small Head - Low Head Small Head - Extra Low Head Small Head *For more details, please refer to the PDF document or feel free to contact us.

This catalog introduces the "tapping screws for resin" handled by Azuma Neji. The nonsert tapping screws for resin feature a smaller flank angle (sharp threads) and a triangular (rice ball) cross-sectional shape of the shaft, which reduces resistance when forming screws in resin products. In addition to the general head shapes (pan, flat, bind), we also offer products with low head heights (related: low head screws) and those designed with recesses to suppress cam-out during installation. [Featured Products] ■ With cross holes ■ With QuaStix holes ■ With hexalobular holes ■ Tools *For more details, please refer to the PDF materials or feel free to contact us.

In fastening, there are many cases where the flexibility and adhesion of rubber are utilized to provide sealing or cushioning functions. However, since rubber alone cannot maintain strength, backup and holding power from metal washers are necessary, which affects cost performance. The "Leak-Proof Washer" has a strong adhesive force due to the vulcanized bonding of metal and rubber, resulting in minimal rubber escape during fastening. This prevents rubber from being caught in the threaded part, maintaining high sealing performance, as well as providing various functions such as vibration resistance, loosening prevention, shock absorption, surface scratch prevention, and insulation. Additionally, in relation to this product, Azuma Screw also offers "Leak-Proof Screws (Nuts)." 【Features】 ■ Strong adhesion of metal and rubber through vulcanized bonding ■ Material: Metal part (stainless steel), rubber part (neoprene, EPDM, etc.) ■ Size: M1 to M20 *For more details, please refer to the PDF document or feel free to contact us.

When the sealing part comes into contact with water, it is necessary to be cautious of leaks from the seat and threaded areas. The "Water Leak Prevention Screw (SEAL LOCK)" is a nut that integrates sealing material, which gets caught in the threaded area during tightening, effectively blocking liquids and gases. Additionally, compared to conventional methods, it is expected to reduce the number of parts and processes, as well as save space. In relation to this product, Azuma Screw also offers "Water Leak Prevention Washers." 【Features】 ■ As it is a single component, it allows for shortened processes and securing of clearance. ■ Can be reused approximately five times. ■ Prevents not only liquid and gas leaks but also loosening. *For more details, please refer to the PDF materials or feel free to contact us.

The "NORD-LOCK washer" is a loosening prevention washer that secures bolts using tension rather than friction resistance. This system consists of a pair of washers, one with a cam surface and the other with a radial rib surface. The angle of the cam (α) is designed to be larger than the lead angle of the screw (β), making it difficult to easily overcome the cam. The wedge effect created by the cam surfaces prevents loosening of the bolt due to rotation. 【Features】 - Prevents loosening caused by intense vibrations and fluctuating loads, ensuring safe fastening. - Can be quickly and easily installed and removed with standard tools. *For more details, please refer to the PDF document or feel free to contact us.
