BS EN ISO 3506-1:2020

This standard BS EN ISO 3506-1:2020 Fasteners. Mechanical properties of corrosion-resistant stainless steel fasteners is classified in these ICS categories:

• 21.060.10 Bolts, screws, studs

This document specifies the mechanical and physical properties of bolts, screws and studs, with coarse pitch thread and fine pitch thread, made of corrosion-resistant stainless steels, when tested at the ambient temperature range of 10 °C to 35 °C. It specifies property classes in relation to austenitic, martensitic, ferritic and duplex (austenitic-ferritic) steel grades for fasteners.

The term “fasteners” is used in this document when bolts, screws and studs are considered all together.

ISO 3506-6 provides general rules and additional technical information on suitable stainless steels and their properties.

Fasteners conforming to the requirements of this document are evaluated at the ambient temperature specified in paragraph 1. It is possible that they do not retain the specified mechanical and physical properties at elevated and/or lower temperatures.

Outside the temperature range of –20 °C to +150 °C, it is the responsibility of the user to determine the appropriate choice for a given application in consultation with an experienced fastener metallurgist and by taking into account e.g. stainless steel composition, duration of exposure at elevated or low temperature, the effect of the temperature on the fasteners mechanical properties and clamped parts, and the corrosive service environment of the bolted joint.

This document applies to bolts, screws and studs:

• with ISO metric thread in accordance with ISO 68-1 ,

• with diameter/pitch combinations in accordance with ISO 261 and ISO 262 ,

• with coarse pitch thread M1,6 to M39, and fine pitch thread M8×1 to M39×3,

• with thread tolerances in accordance with ISO 965-1 and ISO 965-2 ,

• with specified property classes, and

• of any shape.

Stainless steel grades and property classes can be used for sizes outside the diameter limits of this document (i.e. for d < 1,6 mm or d > 39 mm), provided that all applicable chemical, mechanical and physical requirements are met.

Certain bolts, screws and studs might not fulfil the tensile or torsional requirements of this document because of the geometry of their head or unthreaded shank, thus resulting in reduced loadability (e.g. when shear area in the head is less than the stress area in the thread; see 8.2.2).

This document does not apply to set screws and similar threaded fasteners not under tensile stress (see  ISO 3506-3).

It does not specify requirements for functional properties such as:

• torque/clamp force properties,

• shear strength,

• fatigue resistance, or

• weldability.
