What is BS 3777 - Specification for screw thread measuring cylinders about?
BS 3777 is an International Standard that discusses the technical specifications for screw thread measuring cylinders.
BS 3777 relates to two grades of screw thread measuring cylinders intended for use in checking external screw threads by means of pitch diameter measuring machines.
BS 3777 comprises two parts.
Part 1 gives the bases for the diametral tolerances of Grade A and Grade B screw thread measuring cylinders and the relative merits of the two grades.
Part 2 gives the complete specification for both grades of cylinders suitable for the forms and pitches of screw threads
Who is BS 3777 - Specification for screw thread measuring cylinders for?
BS 3777 on the specification for screw thread measuring cylinders is useful for:
- Manufacturers and designers of screw threads
- Manufacturers and designers of screw thread gauges
- Mechanical engineers
- Metrologists
- Testing authorities
- Regulatory authorities
- Quality assurance personnel
Why should you use BS 3777 - Specification for screw thread measuring cylinders?
A screw thread is a ridge wrapped around a cylinder in the form of a helix. Thread measuring cylinders in accordance with BS 3777 are made of steel.
BS 3777 provides user-friendly ideas on the diametral tolerances of grades of screw thread measuring cylinders along with relative merits of Grade A and Grade B screw thread measuring machines. BS 3777 discusses the measuring range of screw thread measuring cylinders to verify the performance characteristics of measuring cylinders which ensures their reliability. BS 3777 provides the form and general dimensions of thread measuring cylinders that help users manufacture good quality, highly efficient products.
The guidelines in BS 3777 provide you with the standardized specification for screw thread measuring cylinders that enable you to provide a superior quality product to the users.
