Hexagonal Locking Nuts for Angle Grinders - China Factory Suppliers for Polishing and Wire Wheel Accessories
Material and Craftsmanship
The main body of the product is made of high-strength 45 # high-quality carbon steel, which is formed by cold heading and strengthened by high-frequency quenching treatment. The hardness reaches HRC42-48, and it has extremely strong resistance to torsion and impact. The surface is coated with white zinc/color zinc anti-corrosion technology, which not only looks beautiful, but also effectively isolates moisture and acid-base corrosion in the air. It has excellent rust prevention ability and is not easy to rust even in harsh working conditions such as rust removal and dust accumulation. Its durability far exceeds that of ordinary nuts.
Structure and specifications
The model has 22 pairs of edges, 24 pairs of edges, 24 pairs of edges, 26 pairs of edges, 24 pairs of double hexagonal edges, and 27 pairs of double hexagonal edges. Adopting standard hexagonal shape and M10/M14/M5/8-11 high-pressure internal thread design:
- Hexagonal shape: Suitable for universal wrenches, with even locking force, completely eliminating looseness and slipping during high-speed rotation.
- Integrated thickened structure: The nut height is sufficient, the thread engagement depth is deep, and it can withstand the high-speed centrifugal force and vibration of the angle grinder at ten thousand revolutions per minute, without easily slipping or loosening.
Core strengths
1. Secure and worry free locking
High precision thread matching ensures a tight fit after tightening, and remains unchanged during high-speed operation, completely eliminating the safety risks of loose or thrown parts.
2. High efficiency of disassembly and assembly, strong adaptability
standard universal thread, perfectly matching the original main shaft of the supporting role mill and various conversion connecting rods, one nut is equipped with 100/125 type grinding discs, realizing "one rod for multiple purposes".
3. High strength and durability, long-lasting
one-piece molding without welding points, compression and impact resistance, no deformation or slipping during heavy-duty operations, making it the preferred durable accessory for decoration, auto repair, and hardware processing.
Main purpose
Widely used for fixing accessories in the modification scenarios of angle grinders and hand drills. Whether it is fixing the steel wire wheel for metal rust removal or welding seam grinding; Fixed cutting blades for stone/metal cutting; Still using a fixed polishing wheel for car paint/furniture polishing, this nut can provide stable locking force and is an indispensable basic accessory in various polishing, cutting, and polishing operations.
Frequently Asked Questions
What materials are these angle grinder lock nuts made of?
The lock nuts are manufactured from high-strength 45# high-quality carbon steel, formed via cold heading and strengthened by high-frequency quenching to achieve a hardness of HRC42-48. This ensures high resistance to torsion and impact.
What thread specifications do you offer for these nuts?
We offer standard internal thread configurations including M10, M14, M5, and 5/8-11 high-pressure internal threads, designed to fit standard angle grinders and hand drill adapters.
How do these nuts prevent rusting in harsh working environments?
The surface of the nuts is treated with white zinc or color zinc anti-corrosion coating. This layer isolates moisture and acid-base corrosion, making them highly resistant to rust even under dusty and humid working conditions.
Will the nut slip or loosen during high-speed rotation?
No. The nut features an integrated thickened structure with deep thread engagement. It is engineered to withstand high-speed centrifugal force and vibration up to 10,000+ RPM without loosening.
What accessories can be fixed using this lock nut?
This nut is suitable for securing steel wire wheels for rust removal, cutting blades for stone or metal, and polishing wheels for automotive paint and furniture polishing.
