CUMMINS
206326 / 3076055 Twelve Point Cap Screw (SCREW,TWELVE POINT CAP) is a professional high-strength locking fastener designed for Cummins series diesel engines. Featuring a twelve-point head structure, this special bolt is widely used for fastening and locking engine key components, sealing covers and mounting assemblies. It effectively solves common mechanical faults such as bolt loosening, thread slipping, fracture and component displacement caused by long-term engine vibration and high-load operation. The twelve-point design provides larger stress area and more stable locking effect, ensuring long-term tight and firm assembly of engine parts.
1. High-Strength Hardened Alloy Steel: Adopts premium alloy steel material with overall quenching heat treatment, achieving high surface hardness and excellent tensile strength. It resists shear force and torsion impact, not easy to break or deform under high vibration working conditions.
2. Unique Twelve-Point Head Design: Multi-angle stress-bearing structure increases contact area with tool, provides more uniform locking force, effectively avoids bolt slipping and rounding during disassembly and assembly, improving installation stability.
3. Precision Thread Machining: Standard precision rolling thread features smooth tooth surface and accurate tolerance, ensuring tight meshing and uniform force bearing. It effectively prevents loosening caused by engine high-frequency vibration.
4. Excellent Anti-Fatigue Performance: Optimized structural toughness adapts long-term cyclic vibration and high-temperature working environment, maintaining stable locking performance without fatigue failure.
5. Anti-Rust & Anti-Corrosion Treatment: Surface passivation and anti-oxidation coating resist erosion of engine oil, moisture and dust, avoiding thread rust and seizure, and extending service life.
6. Accurate Standard Specification: Standard dimension 4.5cm*1.7cm*1.7cm and lightweight 0.032KG perfectly match Cummins engine assembly gaps, supporting plug-and-play replacement without secondary processing.
7. Strict Factory Quality Control: Finished screws pass hardness test, tensile test and thread precision detection, with stable batch quality for engine overhaul maintenance and fleet bulk procurement.
