GB6172 304 A2-70 Stainless Steel Hex Wafer Thin Jam Nut M6–M16 Fine Thread

GB6172 304 A2-70 Stainless Steel Hex Wafer Thin Jam Nut — M6–M16 Fine Thread

GB6172 304 A2-70 stainless steel fine thread hex wafer thin jam nuts combine the low-profile jam nut form with fine thread pitch for automotive, hydraulic, and precision mechanical applications where fine thread provides superior clamping force, vibration resistance, and adjustment precision. The thin wafer profile allows precise torque control and fits in restricted height applications.

Key Specifications

Why Choose Fine Thread Thin Jam Nuts?

• Fine thread + thin profile — dual advantage: fine thread provides superior vibration resistance and clamping force; thin profile allows precise position adjustment and fits restricted height applications
• Jam locking on fine thread assemblies — pairs with a standard fine thread hex nut to create a jam lock on fine thread bolts and studs
• 304 A2-70 stainless — corrosion-resistant for automotive, hydraulic, and outdoor applications
• GB6172 standard — widely specified in automotive and industrial fine thread applications
• M6–M16 range — covers the most common automotive and mechanical fine thread sizes

Typical Applications

• Automotive suspension and steering fine thread jam locking (M10–M16)
• CNC machine ballscrew and linear guide preload fine thread adjustment (M6–M12)
• Hydraulic fitting and manifold fine thread lock nut (M8–M16)
• Precision instrument and optical equipment fine thread adjustment (M6–M10)
• Engine and gearbox component fine thread fastening (M8–M16)
• Motorcycle and bicycle component fine thread assembly (M6–M12)

Frequently Asked Questions

Q: What fine thread pitches are available in M6–M16?

A: Common metric fine pitches: M6×1.0mm, M8×1.0mm or 1.25mm, M10×1.0mm, 1.25mm, or 1.5mm, M12×1.25mm or 1.5mm, M14×1.5mm, M16×1.5mm. Check the specific variant for the exact pitch before ordering.

Q: Can I use a fine thread jam nut on a coarse thread bolt?

A: No. Fine thread and coarse thread nuts are not interchangeable. Always verify the thread pitch of your bolt before selecting a nut. Mixing thread pitches will cross-thread and damage both components.

Q: What is the height of a GB6172 thin jam nut?

A: GB6172 thin jam nut heights (approximate): M6=3.2mm, M8=4.0mm, M10=5.0mm, M12=6.0mm, M14=7.0mm, M16=8.0mm. These are approximately 40–50% thinner than standard DIN934 hex nuts of the same size.
