Stainless Steel Fine Thread Hex Flange Lock Nut DIN6923 M6–M12 304 A2 Serrated Nut

Stainless Steel Fine Thread Hex Flange Lock Nut DIN6923 — M6–M12 304 A2 Serrated Nut

DIN6923 fine thread stainless steel hex flange serrated lock nuts are specified wherever standard coarse thread nuts are insufficient — particularly in automotive, hydraulic, and precision mechanical applications where fine thread pitch provides greater clamping force, finer torque adjustment, and superior vibration resistance. The integrated serrated flange eliminates the need for a separate lock washer.

Key Specifications

Why Choose Fine Thread Flange Lock Nuts?

• Fine thread pitch — smaller thread pitch angle provides greater clamping force per unit torque and inherently better vibration resistance than coarse thread
• Serrated flange — additional mechanical anti-loosening on top of fine thread’s inherent vibration resistance; double protection against loosening
• 304 A2 stainless — corrosion-resistant for automotive, hydraulic, and outdoor applications
• DIN6923 standard — internationally specified; compatible with all fine thread metric bolts and studs of the same pitch
• M6–M12 range — covers the most common automotive and mechanical fine thread sizes

Typical Applications

• Automotive suspension, steering, and drivetrain fastening (M10–M12 fine thread)
• Hydraulic fitting and manifold assembly (M8–M12 fine thread)
• Precision mechanical and optical instrument assembly (M6–M8 fine thread)
• Engine and gearbox component fastening (M8–M12 fine thread)
• CNC machine ballscrew and linear guide mounting (M6–M10 fine thread)

Compatible With

• Fine thread metric bolts: M6×1.0, M8×1.0/1.25, M10×1.0/1.25/1.5, M12×1.25/1.5 (verify pitch before ordering)
• Spanner / socket: M6=10mm, M8=13mm, M10=17mm, M12=19mm AF
• Automotive fine thread studs and bolts

Package Contents

• Fine thread DIN6923 hex flange lock nuts in selected size, pitch, and quantity (per variant)

Frequently Asked Questions

Q: What fine thread pitches are available?

A: Fine thread pitch varies by size. 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. Check the specific variant for the exact pitch before ordering.

Q: Why use fine thread instead of coarse thread?

A: Fine thread provides greater clamping force per unit torque (due to smaller helix angle), better resistance to vibration loosening, and finer adjustment increments. It is preferred in automotive, hydraulic, and precision mechanical applications. Coarse thread is easier to assemble quickly and more tolerant of contamination.

Q: Can I use a fine thread 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 damage both the nut and bolt.
