What is BS 4185-10 - Trapezoidal threads for screw assemblies about?

Trapezoidal thread serves the purpose of producing linear motion when rotated, usually under heavy load. The BS 4185 series discusses standards for machine tool components. BS 4185-10 is a part of the machine tool components series that describes specifications for trapezoidal threads for lead and feed screw assemblies.

BS 4185-10 specifies a range of nominal diameters (10 mm to 100 mm), nominal pitches (2 mm to 20 mm) and tolerances for machine tool lead and feed screws and nuts. BS 4185-10 provides accuracy requirements for assembled screws and nuts, Nominal values of lead, pitch and thread diameter, Dimensions for maximum material profile,

Note: BS 4185-10 does not make any recommendations concerning features such as material, length or mounting criteria for lead and feed screws.

Who is BS 4185-10 - Trapezoidal threads for screw assemblies for?

BS 4185-10 on trapezoidal threads for screw assemblies is useful for:

Manufacturers of screw assemblies and fasteners
Mechanical engineers

Why should you use BS 4185-10 - Trapezoidal threads for screw assemblies?

Trapezoidal thread forms are screw thread profiles with trapezoidal outlines. They offer high strength and ease of manufacture. They are typically found where large loads are required.

BS 4185-10 provides you with accuracy class designations and requirements for assembled screws and nuts. BS 4185-10 gives information that may provide useful guidance when selecting nominal dimensions and accuracy classes, and it may serve to indicate where extra information could be added to the specification if considered necessary.

BS 4185-10 covers dimensions and tolerances specifications related to trapezoidal threads for lead and feed screw assemblies. Following specifications provided in BS 4185-10, lets you manufacture and supply high-quality trapezoidal threads for screw assemblies to your customers. These customers will be able to use trapezoidal threads safely for machine tool applications.
