Mean Mug Auto M6-1.0 x17mm Hex SEMS Bolts with 18mm Washers – Pack of 30, Grade 9.8 Black Phosphate

These are a 30-piece set of M6-1.0 x 17mm hex-head SEMS bolts with 18mm loose washers, made in Grade 9.8 black phosphate as direct replacements for OEM 11508930 for transmission and oil pan applications.

If you need reliable fasteners for an oil pan or transmission pan, these Mean Mug Auto bolts give you a ready-to-install kit that matches common OEM fit and finish. The kit contains thirty M6-1.0 x 17mm hex-head bolts with loose 18mm washers, engineered for automotive service where strength, corrosion resistance, and correct sizing matter. Their black phosphate finish and Grade 9.8 tensile rating make them suitable for under-vehicle locations where vibration and exposure occur.

How do these bolts match OEM specifications?

These bolts are manufactured to replicate the dimensions and form of the OEM 11508930 part number, including thread pitch, head size, and washer diameter. That makes them a direct, drop-in replacement in many applications that originally used that OEM screw. Always verify the washer and head clearances on your specific vehicle model before installation.

• M6-1.0 thread pitch and 17mm length for proper engagement
• 10mm hex head to fit standard sockets and tools
• 18mm loose washer matching many factory pan assemblies
• Interchangeable with OEM part number 11508930

What vehicles and parts are these bolts compatible with?

These M6 fasteners are intended for a broad range of passenger and light-truck applications. They commonly replace pan and body bolts on transmissions and oil pans for brands such as Toyota, Subaru, Dodge, Honda, GM, Nissan, and many others. Compatibility depends on the original bolt size and washer diameter used by the manufacturer.

• Suitable for Toyota, Subaru, Dodge, Honda, GM, Kia, Nissan, Hyundai, Mazda, Acura
• Also fits select Allison, Ram, Sierra, Tundra, Scion and Titan models
• Verify your vehicle’s OEM part number or measure original bolt length and washer size

What materials and durability can I expect?

Constructed from Grade 9.8 steel with a black phosphate finish, these bolts combine high tensile strength with improved surface corrosion resistance versus plain steel. The black phosphate coating helps prevent rust and provides a better base for any additional lubricants during installation. They’re intended for long-term service in underbody locations but should be inspected during major service intervals.

• Grade 9.8 tensile rating for elevated strength under load
• Black phosphate finish for corrosion resistance
• SEMS loose washer design prevents loss during assembly
• Pack of 30 for complete pan replacement or spares

How should I select and install these bolts safely?

Before installation, confirm the 18mm washer will clear your pan flange and that 17mm bolt length provides proper thread engagement without bottoming out. Use a calibrated torque wrench and follow the vehicle manufacturer’s torque sequence and values. Replace any damaged washers or fasteners and inspect mating surfaces for flatness to ensure a leak-free seal.

• Measure original bolt length and washer diameter before ordering
• Use manufacturer-specified torque settings and tightening sequence
• Inspect pan flange and gasket surface before reassembly
• Keep extra bolts on hand — kit includes 30 pieces
