Understanding ASME B18.64: The Standard for Metric Helical Coil Inserts
If you are searching for "ASME B1864 pdf," you are likely looking for the ASME B18.64 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).
Self-tapping screws are a critical component in modern assembly processes, especially in the construction, automotive, and electronics industries. These screws can tap their own threads into a material, usually metal, without pre-drilling a hole, which streamlines assembly processes and reduces production costs. The American Society of Mechanical Engineers (ASME) publishes standards for various mechanical components, including fasteners like self-tapping screws. ASME B18.64 is the standard that provides specifications for self-tapping screws, ensuring they are manufactured and perform to certain criteria. asme b1864 pdf
Performance Reliability: The standard dictates the hardness, torque limits, and drive styles (like Phillips, Slotted, or Torx) required to prevent failure. Understanding ASME B18
The standard specifies requirements for several fastener types designed to create their own threads in metal, wood, or plastic. Key technical areas include: Fasteners Clearing House Fastener Types Thread-Forming Screws especially in the construction
Need help identifying another ASME fastener standard? The B18 committee covers over 70 documents, from hex nuts (B18.2.2) to cotter pins (B18.8.1). Double-check your standard number before purchasing.
The applications of self-tapping screws, and by extension, the ASME B18.64 standard, are vast. They are commonly used in:
- Insert configurations (free-running and screw-locking types)
- Tapped hole dimensions for insert installation
- Driving tool and tang break-off notch dimensions
- Tensile strength and proof load testing
1. Obsolete Data (Safety Hazard)
Even if you stumble upon a real standard (like old B16.5 from 1996), using outdated dimensions can lead to flange leaks, bolt failures, or catastrophic pipe ruptures. ASME updates standards every two years for safety reasons.
