Stainless Steel Hex Flange Flat Point Screws Coarse Thread With Serration

Our Stainless Steel Hex Flange Flat Point Screws With Serration and Coarse Thread are professional heavy-duty industrial fasteners, uniquely optimized for solving the problems of insufficient gripping force and easy vibration loosening of ordinary flange screws. This product innovatively adds precision ribs anti-slip texture under the hex flange head. The uniform and delicate raised texture can form a tight biting fit with the mounting surface after locking, greatly increasing static friction, effectively restraining screw rotation and back-off, and solving the long-standing vibration loosening defect of industrial fastening screws. Different from conventional fine thread screws, it adopts standard industrial coarse thread design with larger tooth pitch, deeper tooth profile and wider meshing range. The coarse thread has stronger anti-loose performance and higher load-bearing limit, which can firmly bite thick wood, steel and composite thick plates, providing stable heavy-load fastening effect. The optimized flat point structure abandons the traditional sharp drilling tip, with flat and smooth Point surface, which will not pierce or damage thick substrates during locking, effectively protecting the structural integrity of thick workpieces. The integrated one-piece hex flange head has large bearing area and uniform pressure dispersion, avoiding local pressure concentration and substrate crushing. Made of high-strength stainless steel, the whole screw has excellent wear resistance, vibration resistance and anti-rust performance, maintaining long-term stable heavy-load locking performance in harsh industrial working environments, becoming reliable anti-loose heavy-duty fasteners for industrial engineering.

Key Features

- Under-Head Precision ribs: Exclusive ribs anti-slip texture under the flange head, super friction biting force, effectively resists mechanical vibration and prevents screw loosening and back-off.

- Industrial Coarse Thread Design: Large tooth pitch and deep tooth depth structure, stronger bite force and pull-out resistance than fine threads, excellent heavy-load bearing and anti-loose performance.

- Protective Flat Point Structure: Flat smooth Point surface, no sharp piercing force, avoids thick substrate piercing and surface damage, fully protects workpiece integrity.

- One-Piece Hex Flange Head: Large-area pressure-bearing flange structure, uniform stress dispersion, strong pressure resistance, no local crushing or deformation during heavy-load locking.

- High-Strength Stainless Steel Material: Excellent vibration resistance, wear resistance and anti-corrosion performance, stable performance in long-term industrial heavy-load working scenarios.

- Heavy-Duty Anti-Loose Performance: ribs anti-slip + coarse thread self-locking dual protection, ultra-high anti-loose stability for vibration-intensive industrial environments.
