Product Description
Product Overview
This product is a hexagon socket flat point set screw (grub screw), made of carbon steel and heat-treated to achieve ultra-high strength of Grade 12.9, with black oxide surface treatment and pre-coated anti-loosening adhesive (dot adhesive). Its flat point design provides a large contact area, suitable for occasions where the pressure on the part surface needs to be evenly distributed or indentation needs to be avoided. The pre-coated anti-loosening adhesive cures after the screw is tightened, forming strong friction and adhesion, achieving top-level shockproof and anti-loosening effects, especially suitable for permanent or high-reliability locking in high-vibration environments.
Core Advantages
-
Top-Level Anti-Loosening and Shock Resistance: Pre-coated with high-performance anti-loosening adhesive, which provides excellent anti-vibration and anti-loosening capabilities after curing, with extremely high reliability.
-
Ultra-High Mechanical Strength: Grade 12.9 strength ensures that the screw body can withstand extremely high preload and load.
-
Protect Contact Surface: The flat point design avoids embedding into the part surface like a cone point, suitable for occasions that need to protect the contact surface or be used on harder materials.
-
Multiple Precision Grades Available: Grade C/B/A precision is provided to meet the assembly needs of different levels from general equipment to precision instruments.
Applicable Industries
-
Heavy-Duty Vibration Equipment: Positioning and locking of bearings and bushings in high-strength vibration environments such as construction machinery, mining machinery and vibrating screens.
-
Automotive Power Train: Permanent locking of key components under high-frequency vibration inside engines and transmissions.
-
High-Speed Rail Transit: Fastening points requiring extremely high anti-loosening reliability such as locomotive transmission systems and bogie auxiliary components.
-
Energy and Power Generation Equipment: Connections that bear long-term complex loads such as wind turbine gearboxes and gas turbine auxiliary components.
-
Precision Machine Tools and Spindles: Adjustment and fixation of machine tool spindles, turrets, rotary tables, etc. that require high precision and anti-loosening.
-
Aerospace Equipment Auxiliary Structures: Non-flight critical parts with extreme anti-loosening requirements such as aircraft ground maintenance equipment and test benches.
Warm Tips
-
The adhesive is pre-coated; after installation, a certain time (usually 24 hours) is required to reach full curing strength, during which please avoid equipment operation.
-
Please keep the threaded hole clean and free of oil before installation to ensure the anti-loosening adhesive achieves the best bonding effect.
-
Black oxide treatment mainly provides basic rust prevention and appearance; anti-loosening mainly relies on the adhesive, and re-adhesive coating may be required after disassembly.
