ISO 888 is an international standard on fasteners that discusses the lengths and thread lengths of fasteners for manufacturing precise parts. ISO 888 specifies lengths and thread lengths for bolts, screws, and studs for use inappropriate product standards and other relevant documents, e.g. for parts per drawing. It applies to bolts, screws, and studs with ISO metric screw thread according to ISO 68‑1.
ISO 888 on fasteners is relevant to:
The axial distance through which the fully formed threads of both the nut and bolt are in contact is called the length of thread engagement. The "nominal length" of a measure of length is the length by which that measure is designated.
ISO 888 provides guidance on the position of lengths and thread lengths, dimensions for lengths, dimensions for thread lengths.
ISO 888 exemplifies the required dimensions that help you achieve precision in terms of product functionality. With obedience and compliance to ISO 888, you can efficiently manufacture high-quality precise bolts, screws, and studs. ISO 888 helps you to build consumer trust and confidence in the product.
