Product Description
Product Overview
This product is a set screw with a nylon head. The screw body is made of Grade 8.8 medium carbon steel and nickel plated, with nylon material inserted at one end of the head. This design combines the strength of the metal screw with the elasticity and self-locking property of nylon. When tightened, the nylon part produces elastic deformation and fills the thread gap, forming effective frictional locking to achieve excellent shockproof and anti-loosening effects, without the need for additional glue or washers.
Core Advantages
-
Efficient Anti-Loosening and Shock Resistance: The nylon head deforms and expands when locked, generating continuous friction force to effectively resist vibration and loosening.
-
No Need for Additional Locking Elements: Integrated nylon locking structure simplifies the assembly process and reduces overall costs.
-
Reliable Connection Strength: The Grade 8.8 medium carbon steel body provides sufficient mechanical strength and clamping force.
-
Corrosion Resistance and Attractive Appearance: The nickel-plated surface provides good rust protection and a bright appearance.
Applicable Industries
-
Automotive Components: Fastening points requiring shockproof and anti-loosening, such as engine accessories, interior parts, and wire harness fixing brackets.
-
Electronic and Electrical Equipment: Anti-loosening fixation of internal PCB mounting posts and terminal blocks in frequency converters, servo drives, and control cabinets.
-
Household Appliances: Fastening of internal structural parts and brackets in vibration environments such as air conditioners, washing machines, and refrigerators.
-
General Mechanical Equipment: Connection of equipment parts with continuous vibration such as fans, pumps, and conveyor motors.
-
Outdoor Facilities and Furniture: Assembly points requiring anti-loosening such as outdoor lighting, traffic facility signs, and steel-wood furniture.
-
Bicycles and Sports Equipment: Locking of manually frequently adjusted parts such as bicycle components and fitness equipment adjustment knobs.
Warm Tips
-
During installation, please ensure that the nylon head end faces the force-locking direction, and tighten to the specified torque to ensure that the nylon is fully deformed to exert the locking effect.
-
It is not recommended to use it in a long-term high-temperature environment exceeding the rated temperature of the nylon material (usually below about 120℃).
-
Excessive repeated disassembly may reduce the locking force of the nylon part; please pay attention to the maintenance cycle in key parts.
