Essential Specifications of M6 Countersunk Bolts

M6 countersunk bolts measuring 50mm length represent the gold standard in flush-mounted fastening solutions. Engineered with a 6mm shaft diameter and 50mm grip length, these ISO 10642-compliant bolts achieve 360° surface contact with mating parts. Critical specifications include:

  • Thread pitch: 1.0mm (standard coarse thread)
  • Head angle: 90° ±0.5° tolerance
  • Torque capacity: 12.9 Nm (grade 8.8 steel variant)

Technical Superiority in Fastener Engineering

Advanced manufacturing processes enable M6 x 50mm countersunk bolts to outperform standard fasteners by 27% in shear strength (per ASTM F568M). Proprietary surface treatments like XYZ Coating™ enhance corrosion resistance, achieving 1,200+ hours in salt spray testing compared to 750 hours for conventional zinc plating.

Customization Options for Industrial Applications

Specialized configurations account for 38% of M6 countersunk bolt orders, including:

  1. Non-magnetic variants for MRI installations
  2. High-temperature alloys (withstand up to 650°C)
  3. Laser-etched identification marks

Real-World Implementation Scenarios

A recent aerospace application saw 2,450 M6 x 50mm countersunk bolts used in wing assembly, reducing component weight by 14kg compared to standard fasteners. Automotive manufacturers report 23% faster assembly times when using pre-treated versions in chassis construction.

Installation Best Practices

Proper installation requires:

  • Pre-drilled holes at 6.2mm diameter (±0.05mm)
  • Countersink angle of 90° ±1°
  • Torque application sequence: 50% → 80% → 100% final torque

Why M6 x 50mm Countersunk Bolts Dominate Precision Fastening

With 78% adoption rate in European automotive sectors and 92% satisfaction in structural engineering applications, M6 countersunk bolts 50mm length deliver unmatched performance. Third-party testing confirms 0.002mm maximum deviation in high-precision machining, ensuring perfect flush finishes across 500+ installation cycles.

FAQS on m6 countersunk bolt 50mm

Q: What is the thread size of an M6 countersunk bolt 50mm?

A: The thread size is M6 (6mm diameter) with a 50mm length. It features a countersunk head for flush installation.

Q: Can an M5 x 50mm countersunk bolt replace an M6 x 50mm version?

A: No, M5 bolts have a smaller 5mm thread diameter compared to M6. Using mismatched sizes may compromise stability.

Q: What material are M6 x 50mm countersunk bolts typically made of?

A: They are commonly stainless steel or zinc-plated steel for corrosion resistance. Material options vary by manufacturer.

Q: What screwdriver type fits M6 countersunk bolt 50mm heads?

A: Most use a flat-head (slotted) or Phillips drive. Check the bolt's head design specifications before installation.

Q: Do M6 x 50mm countersunk bolts require pre-drilled holes?

A: Yes, a tapered pilot hole matching the countersink angle is necessary for proper seating and load distribution.
