Features the same thread pitch as Type B but possesses the gimlet point of Type A. It offers better starting characteristics in thin metal.
What you are fastening into (e.g., sheet metal, plastics, cast iron)? The head style or drive type required for your assembly? Any specific torque or load requirements you must meet?

Optimized with specialized wide cutting slots for fast material removal. Type 25 is uniquely engineered for soft plastics and thermal materials. 3. Metallic Drive Screws
A low-profile head with a flat top surface and high edge walls, providing high clamping force.
If you look at the alphanumeric string, B1864 visually merges B1.20.1 and B16.4 into a single, non-existent number. It is highly likely that a user searching for "ASME B1864 PDF" actually needs information regarding (B1.20.1) or cast iron threaded fittings (B16.4). In some cases, users may also be confusing it with the obsolete MIL-P-1864 military specification for hose couplings. Features the same thread pitch as Type B
These fasteners feature specialized cutting edges, slots, or flutes on the lead threads that physically remove material to tap a hole as they are driven. They reduce driving torque in harder materials. Common types include:
This standard establishes pressure-temperature ratings, dimensions, tolerances, and markings for (classes 125 and 250). These fittings are ubiquitous in:
The standard specifies dimensions for several drive configurations: Phillips (Type I) Frearson (Type II) Pozidriv (Type IA) Hex socket Mechanical and Performance Requirements The head style or drive type required for your assembly
If you are searching for "ASME B1864 pdf," you are likely looking for the standard. This is a common typo or misremembered number, as the ASME B18 series covers fasteners, and B18.64 specifically addresses metric helical coil screw thread inserts (commonly known as wire thread inserts or Heli-Coil® type inserts).
Beyond dimensions, the standard specifies the physical performance criteria that these fasteners must meet. This includes:
