| Product Name | Notes |
|---|---|
| Compared to SUS304, SUS310S has excellent heat resistance, oxidation resistance, and nitric acid resistance compared to SUS304. Austenitic series stainless steel with high Ni content, which is effective for corrosion... | |
| Flat washers for high intensity screws. The surface area is twice or more of that of standard washers. Washers eliminate bolt looseness by preventing the sinking of the bearing surface. | |
| Plain washers for high strength stainless steel bolts. Hardness is 300 HV or higher. Even higher hardness than general stainless steel plain washers. Suited to use with stainless steel bolts... | |
| Ribs on both sides of the washer hook onto the bolt bearing surface and intended attachment section to prevent looseness due to vibration. Washers for loosing prevention. For connecting locations... | |
| Screws show excellent corrosion resistance against oxidizing and reducing by inorganic and organic acids.⇒The Properties of Screws Made of Special Materials Excellent resistance to stress corrosion cracking caused by hydrogen... | |
| Seal washer incorporating rubber packing in a stainless steel washer. Prevents air/liquid leakage from the seating surface of the screw head. During screw tightening, the rubber bonds with the screw... | |
| Sealing washers with a built-in rubber seal. Sealing washers prevent the leakage of gas and liquid from the bearing surface of the screw head. The washer body is coated with... | |
| Specific gravity is approximately 60% of stainless steel. Nonmagnetic. Excellent chemical and seawater resistance. Chemical polishing and brightening processing improve the screw surface. Furthermore, the screws are cleanroom washed, cleanroom... | |
| Stainless steel sealing washers with a built-in rubber seal. Washers prevent the leakage of gas and liquid from the bearing surface of the screw head. Test results for JIS C... | |
| Stainless steel sealing washers with a built-in rubber seal. Washers prevent the leakage of gas and liquid from the bearing surface of the screw head. The rubber does not escape... | |
| The ventilation groove easily releases gas trapped in the drill holes of equipment and machines, and supports vacuum drawing of vacuum devices. Cleanroom wash and cleanroom packing are completed.⇒Cleanroom Wash... | |
| There is a variety of outside diameters and thickness relative to normal plain washers. For securing seating surface on the long hole position and engagement of materials with low marginal... | |
| These nuts and washers are made of pure molybdenum. Melting Point: 2623 deg C. Excellent heat resistance. | |
| Use a concave and convex set. Washers can absorb a tilt of the bolt and bearing surface to a maximum of 2°. | |
| Vibration resistant treatment effect can be achieved simply by using commercially available hexagon nuts. Hexagon nuts can be tightened by hand until tightening force applies, for simple mounting. Use the... | |
| Washer for Flat Head Screw. A Flat Head Screw can be used without countersinking. It decorates the mounting part beautifully by sleek spherical shape. | |
| Washers suitable for positioning and fixing slide mechanisms using slotted holes. The projection on the washer seating surface prevents the washer from turning and the pointer on the top always... | |
| When the thread part and mating side materials differ, this prevents the corrosion (galvanic corrosion *1) that occurs due to adherence of water droplets, etc. The surface treatment reduces the... |
