Full title and description

ISO 10510:2011 — Tapping screw and washer assemblies with plain washers. This International Standard specifies the characteristics and requirements for tapping screws supplied with captive plain (flat) washers: thread sizes ST2.2 to ST9.5 inclusive, flat seating heads and mechanical properties as specified in ISO 2702. The plain washers are captive (non‑removable) and free to rotate.

Abstract

ISO 10510:2011 defines dimensional and mechanical requirements for tapping screw and plain washer assemblies intended for sheet‑metal applications. It covers thread size range ST2.2–ST9.5, head seating form (flat seating), and references ISO 2702 for mechanical property classes. The standard was published as Edition 2 in April 2011 and replaces the 1999 edition.

General information

• Status: Published (Edition 2, confirmed on systematic review).
• Publication date: April 2011 (Edition 2).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 21.060.10 (Fasteners).
• Edition / version: Edition 2 (2011).
• Number of pages: 4 (ISO published pagination; national/adopted documents may show different page counts).

Scope

This standard specifies requirements for tapping screw and plain washer assemblies with spaced threads from ST2.2 to ST9.5 inclusive. It applies to assemblies having a flat seating head and captive plain washers (washers formed or fitted so they cannot be removed but may rotate). Mechanical property requirements are given by reference to ISO 2702. The document provides dimensional, mechanical and functional criteria necessary to ensure interchangeability and fitness for typical sheet‑metal fastening applications.

Key topics and requirements

• Thread size range: ST2.2 to ST9.5 (inclusive).
• Flat seating head geometry and seating surface requirements.
• Plain (flat) washer captive design — washers prevented from disassembly but able to rotate.
• Mechanical property classes and testing referenced to ISO 2702.
• Dimensional tolerances and acceptance criteria for assemblies.
• Normative references that define related fastener dimensions and terminology (e.g., ISO 10669, ISO 1478, ISO 2702, ISO 1891).

Typical use and users

Used by fastener manufacturers, product designers, OEMs, procurement and quality engineers, and standards committees to ensure consistent performance and interchangeability of tapping screw + plain washer assemblies in sheet‑metal assemblies (electronics enclosures, appliance housings, metal furniture, construction components, etc.). Also used by testing laboratories and conformity assessment bodies when verifying mechanical properties and dimensions.

Related standards

FAQ

Q: What is this standard?

A: ISO 10510:2011 is an International Standard that specifies requirements for tapping screw and plain washer assemblies with captive (non‑removable) flat washers and flat seating heads, covering thread sizes ST2.2 to ST9.5.

Q: What does it cover?

A: It covers dimensional and mechanical requirements for the assemblies, specifies the captive plain washer form (washers fixed to the screw but free to rotate), and references ISO 2702 for mechanical property classes and tests.

Q: Who typically uses it?

A: Fastener manufacturers, product designers, OEMs, procurement and quality engineers, testing laboratories, and standards bodies involved in specifying or verifying tapping screw + washer assemblies for sheet‑metal applications.

Q: Is it current or superseded?

A: ISO 10510:2011 is Edition 2 published in April 2011 and replaced the 1999 edition. It was confirmed on ISO systematic review cycles; users should check national adoption documents for the most recent national status, but the 2011 edition is the current ISO edition.

Q: Is it part of a series?

A: It is a standalone ISO standard within the fasteners family but is closely related to other ISO fastener standards (for example ISO 2702, ISO 10669, ISO 1478 and ISO 1891) and is often published/adopted together with regional (EN/SS/NEN/SFS) implementations.

Q: What are the key keywords?

A: Tapping screw, plain washer, captive washer, flat seating head, ST2.2–ST9.5, mechanical properties, ISO 2702, fasteners.
