NISSAN 08360-41226 Hex Head Machine Screw with Washer

The genuine OEM Nissan hex head machine screw with washer (part number 08360-41226) provides reliable and durable mechanical fastening across various structural assemblies of the vehicle. Precision thread machining and factory-specification surface treatment ensure optimal clamping force and vibration resistance in automotive applications.

Technical Specifications:

• Manufacturer: NISSAN (Genuine OEM part)
• OEM Part Number: 08360-41226
• Reference / Interchange Part Numbers: 0836041225
• Design: Hex head machine screw with captive rotating washer (SEMS design)
• Function: Vibration-resistant fastening, even surface load distribution
• Material Quality: High-tensile steel with automotive-grade anti-corrosion coating

Function and Significance:

Machine screws with integrated washers (SEMS screws) are critical fastening components at vehicle mounting points. The integrated washer increases the contact surface area, preventing deformation or damage to joined mating surfaces when the specified tightening torque is applied. Furthermore, it provides dependable protection against loosening caused by engine and chassis vibrations, which is essential for maintaining long-term structural integrity.

Wear Symptoms and Replacement:

Fastener replacement is strongly recommended during disassembly repairs, especially if thread stretching, stripping, or deformation is present, if the hex head corners are rounded from tool wear, or if surface corrosion compromises the structural material. Improperly torqued, deformed, or reused fasteners can lead to component loosening and mechanical failure.
