Full title and description

ISO 4017:1988 — Hexagon head screws — Product grades A and B. This edition specifies dimensional and product-grade requirements for hexagon‑head screws with thread up to the head (fully threaded) in metric sizes, and defines the two product grades (A and B) covered by the standard.

Abstract

ISO 4017:1988 sets out preferred thread sizes, nominal lengths and thread lengths, head and point form, and applicable product grades for fully threaded metric hexagon‑head screws (threads M1.6 to M64). It references related ISO thread and fastener standards for tolerances, mechanical properties and surface treatment. The 1988 edition was later withdrawn and superseded by subsequent revisions of ISO 4017.

Scope

This International Standard specifies requirements for hexagon head screws with threads from M1.6 up to and including M64, with product grade A applying for threads M1.6 to M24 (and nominal lengths up to 10d or 150 mm, whichever is shorter) and product grade B for larger sizes or longer nominal lengths. It covers dimensional data (preferred threads, head sizes, chamfer/point form), thread length guidance for fully threaded parts, and references for mechanical and surface requirements. For specialized requirements the standard points users to related ISO documents (threads, mechanical properties, tolerances, coatings).

Key topics and requirements

• Definition of hexagon‑head screws with full thread (thread to head) and delineation of product grades A and B.
• Preferred metric thread sizes covered: M1.6 up to M64 and associated standard pitches.
• Dimensional tables for head dimensions, thread lengths, chamfer/point form and acceptable tolerances.
• References to general ISO thread and fastener standards for limits, tolerances and mechanical property classes (for example ISO 261, ISO 965, ISO 898‑1, ISO 4759‑1).
• Notes on interchangeability with related hexagon head bolt standards (differences vs. partially threaded bolts covered by ISO 4014).

Typical use and users

Engineers and designers specifying metric fasteners for mechanical assemblies, manufacturers of fasteners, quality assurance and inspection laboratories, procurement specialists, and maintenance professionals use this standard (or its successors) to ensure correct dimensions, thread compatibility and product grades for fully threaded hexagon‑head screws. The standard is relevant in general engineering, machinery, construction and OEM component production.

FAQ

Q: What is this standard?

A: ISO 4017:1988 is an International Standard that defined dimensional and product‑grade requirements for fully threaded metric hexagon‑head screws (product grades A and B).

Q: What does it cover?

A: It covers nominal sizes (M1.6 to M64), preferred pitches, head dimensions, thread lengths for fully threaded screws, point/chamfer details and references to mechanical/tolerance/surface standards needed to specify a complete fastener.

Q: Who typically uses it?

A: Fastener manufacturers, mechanical designers, procurement and quality/inspection personnel, and maintenance engineers who need consistent dimensional and product‑grade definitions for fully threaded hexagon screws.

Q: Is it current or superseded?

A: The 1988 edition has been withdrawn; ISO 4017 has been revised in later editions (notably ISO 4017:1999 and subsequent updates). Users should refer to the latest edition of ISO 4017 for current requirements.

Q: Is it part of a series?

A: Yes—ISO 4017 belongs to the family of ISO fastener standards (for example ISO 4014 for partially threaded hexagon head bolts) and is linked by references to general thread, tolerance and mechanical property standards (ISO 261, ISO 965, ISO 898‑1, ISO 4759‑1, etc.).

Q: What are the key keywords?

A: Hexagon head, full thread, metric screw, product grade A, product grade B, ISO 4017, M1.6–M64.
