1. Thread Types (per DIN 910):

Metric Threads: ISO Metric coarse thread (e.g., M10, M12, M20, M30, etc.)

G-Threads (BSPP): Often used in fluid systems, e.g., G 1/4", G 1/2", G 1", etc.

Threads are cylindrical (parallel) – designed for use with flat sealing faces.

2. Head Type:

Hexagon Head (external) – designed for tightening/loosening with a standard spanner or socket wrench.

Head size increases with thread size, consistent with ISO standards.

3. Sealing Surface:

Face Seal under the head – provides reliable sealing without additional sealant in many applications.

Can be used with sealing washers or tape for additional protection (especially in gas or high-pressure systems).

🛠️ Installation and Use

Torque tightening is important for proper sealing (torque values depend on thread size and material).

Suitable for direct metal-to-metal sealing – especially effective in precision-machined threaded holes.

May require thread sealant (e.g., PTFE tape or Loctite) for gas-tight or hydraulic-tight seals in dynamic environments.

🌡️ Temperature and Pressure Resistance

Material Typical Temperature Range Pressure Rating

Steel (zinc-plated) -20°C to +120°C Up to 250 bar (depends on size/thread)

Stainless Steel (A2/A4) -50°C to +400°C Up to 400 bar

Brass -20°C to +200°C Up to 150 bar

Note: Ratings vary based on thread size, wall thickness, and sealing surface finish.

📐 Dimensions and Standards

DIN 910 includes a dimensional table specifying:

Thread size (e.g., M10 × 1.5, M20 × 2.5)

Head dimensions (across flats, head height)

Thread engagement length

Tolerances (usually ISO 965-1 / 965-2)

You can refer to the official DIN 910 specification sheet or ISO equivalent for precise dimension tables.
