High Strength Bolt, Nut, Washer
Construction high-strength bolts, nuts, washers - 20,000 tons/year production capacity HIGH STRENGTH BOLT, NUT, WASHER TORQUE SHEAR BOLT, NUT, WASHER HEX CAP SCREW (CLASS 4.6, 8.8, 10.9, 12.9) HEX NUT (CLASS 8, 10, 12) Heavy-duty truck bolts, nuts - 10,000 tons/year production capacity
Strongly bonded with metal and rubber through vulcanization! Sizes available from M1 to M20.
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 "water leak prevention washer" has a strong adhesive force due to the vulcanized bonding of metal and rubber, resulting in minimal rubber displacement 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, vibration absorption, surface scratch prevention, and insulation. Additionally, in relation to this product, Azuma Neji also offers "water leak prevention 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.
We respond to needs with mill sheets and inspection certificates! Please consider our proposal when estimating drawings with specification requirements.
This product is a flat washer with a hardness classification of 300HV. It prevents the nut or bolt head from sinking into the joined materials. It can be used when the hole diameter is larger than the bolt diameter or to stabilize the seating surface. It meets needs with a mill sheet and inspection certificate. The material used is S45C to S55C (domestic material), and it has undergone bright hardening and tempering heat treatment. 【Features】 ■ JIS B1256:2008 ■ Standard shape/Part grade A ■ With marking ■ Hardness classification of 300HV ■ With mill sheet and inspection certificate *For more details, please refer to the PDF document or feel free to contact us.
The wedge-shaped teeth effectively suppress the rotation of looseness! Available for light and heavy loads.
The "SUS CDW" is a serrated hexagonal spring washer. Its dish spring shape supports axial force through spring reaction. The wedge-shaped serration effectively suppresses the rotation of loosening. It has a wedge shape that is less likely to damage the joined components, and it is made of SUS304, which has high heat resistance, making it usable even in high-temperature environments. 【Features】 ■ Supports axial force through spring reaction with a dish spring shape ■ Effectively suppresses the rotation of loosening with wedge-shaped serration ■ Wedge shape that is less likely to damage the joined components ■ High heat resistance with SUS304, usable in high-temperature environments ■ Material: S50C to S70C, SUP10; Hardness: 40 to 48 HRC *For more details, please refer to the PDF document or feel free to contact us.
The design makes it difficult for the rubber to protrude even when tightening to the appropriate torque! It seals the fluid on the side.
At Sanwa Ai, we handle "seal washers." This is a set product that incorporates a rubber packing into a metal-formed bowl-shaped washer. The rubber packing is press-fitted onto the threaded part of the bolt, sealing fluids at the side. Designed to minimize rubber overflow even under proper torque tightening, we use SUS304, which is resistant to rust, as the standard material, and offer packings made of NBR (standard specification), silicone, fluororubber, and EPDM. 【Features】 - Suitable for preventing gas and liquid leakage - Passed pressure tests of 200 atmospheres (20 MPa) - Provides sufficient performance even when used directly on the surfaces of black steel and cast iron - Vibration damping and soundproofing effects - Metal and rubber packing do not resonate with vibrations *For more details, please refer to the PDF materials or feel free to contact us.
Introducing a washer that strongly seals fluids with a rubber packing that deeply embeds into the threaded part of the bolt!
