M1.6-0.67×10 screws are a type of metric fastener that play an essential role in precision engineering and small-scale assemblies. In simple terms, the designation tells you that the screw has a nominal outer diameter of 1.6 mm, a thread pitch of 0.67 mm, and an overall length of 10 mm. This guide will take you through each element of this specification and explain its importance in both design and practical application.
Overview of Metric Fasteners
Metric fasteners are standardized worldwide, ensuring that parts manufactured in different regions meet the same technical criteria. With the introduction of ISO standards, screws like the M1.6-0.67×10 have become reliable components in everything from electronic devices to high-tech aerospace applications.
Breaking Down the Designation
Understanding M1.6-0.67×10 is simple once you know the basics:
- The “M1.6” denotes the nominal outer diameter (1.6 mm).
- The “0.67” represents the distance between adjacent threads (pitch).
- The “x10” indicates the length of the screw (10 mm).
Understanding the Specification
The technical aspects of M1.6-0.67×10 screws are critical in ensuring they perform as expected in various applications.
Detailed Analysis of “M1.6”
The “M1.6” portion signifies that the screw is designed with a 1.6 mm nominal diameter. This measurement is key when designing small assemblies, ensuring that the screw fits correctly in pre-drilled holes and interfaces perfectly with corresponding nuts and threaded holes.
Explaining the “0.67” Pitch
A pitch of 0.67 mm indicates a fine thread structure. A fine pitch provides a higher number of threads per unit length, which is ideal for applications requiring precise engagement and minimal play between fasteners. This finer engagement distributes loads more evenly and can improve the screw’s holding power in delicate assemblies.
The Importance of “x10” Length
The “x10” component specifies that the screw’s length is 10 mm. This length is crucial for applications where space is limited and precision is required. A 10 mm screw is often used in micro-assemblies, electronics, and other devices where every millimetre counts.
Below is a table summarizing the key specifications of M1.6-0.67×10 screws:
