Stainless Steel Hex Nut Type 1 with Nylon Locking Feature

Stainless Steel Hex Nut Type 1 with Nylon Locking Feature

Stainless Steel Hex Nut Type 1 with Nylon Locking Feature

Specification: JIS Annex Standard Type 1 (Single-sided) This is a type 1 stainless steel hex nut with a Nylock treatment on the threaded part. It complies with EU-RoHS2 standards. - About the anti-loosening treatment Nylock is a reliable anti-loosening processing technology that permanently adheres special nylon to the threaded part. The principle of Nylock's anti-loosening is that when the screw is tightened, the elastic rebound force of the adhered special nylon generates a strong frictional bonding force across the entire threaded part on the opposite side of the processed area, providing a permanent anti-loosening function against vibrations and shocks. It demonstrates exceptional anti-loosening effectiveness in frequently used locations. This offers advantages not found in bonded anti-loosening products or lock nuts that deform the threaded part. Nylock is a registered trademark of Nylok LLC. *Please contact us separately as specifications may change when used in critical safety areas such as railway vehicles, aircraft, and military applications.

Stainless Steel (Low Temperature Black Chrome Treatment) Hex Nut - Type 2

Stainless Steel (Low Temperature Black Chrome Treatment) Hex Nut - Type 2

Stainless Steel (Low Temperature Black Chrome Treatment) Hex Nut - Type 2

This is a stainless steel hex nut treated with a thin film of high corrosion resistance and matte black "low-temperature black chrome treatment," conforming to two types of JIS supplementary standards (double-sided). The non-glossy black surface is ideal for optical devices that require anti-glare properties. It has corrosion resistance several tens of times greater than black dyeing. The low-temperature black chrome treatment offers excellent wear resistance, light-selective absorption, and thermal absorption, leading to increased demand in industries related to semiconductors, liquid crystals, and optical technology. It complies with EU-RoHS2 standards. Applications: Semiconductor and liquid crystal manufacturing equipment, optical inspection equipment, top covers and diaphragm parts of high-end single-lens reflex digital cameras, precision drive components such as LM guides and gears, etc. Standard film thickness: 3 to 12 μm. Since there is no need to apply oil, it can be used in clean rooms.

Stainless Steel (Low Temperature Black Chrome Treatment) Hex Nut - Type 3

Stainless Steel (Low Temperature Black Chrome Treatment) Hex Nut - Type 3

Stainless Steel (Low Temperature Black Chrome Treatment) Hex Nut - Type 3

This is a stainless steel hex nut with a high corrosion-resistant, matte black "low-temperature black chrome treatment" applied to its surface. It is a type that conforms to JIS supplementary standard category 3 (low-profile double-sided). It can be combined with JIS category 1 or 2 hex nuts and used as a double nut. The non-glossy black surface is ideal for optical devices that require anti-glare properties. It has corrosion resistance that is tens of times greater than black dyeing. The low-temperature black chrome treatment offers excellent wear resistance, light-selective absorption, and heat absorption, leading to increased demand in industries such as semiconductors, liquid crystal, and optical technology-related equipment. It is compliant with EU-RoHS2 standards. Applications: Semiconductor and liquid crystal manufacturing equipment, optical inspection equipment, top covers and diaphragm parts for high-end single-lens reflex digital cameras, precision drive components such as LM guides and gears.
