From basic specifications to advanced techniques — become a screw identification expert
What is the M series? What's the difference between UNC and UNF? Thread pitch, thread angle, head type classification — understand the fundamentals of screw specifications.
How to use calipers? How to use thread pitch gauges? The difference between outer diameter, pitch diameter, and head diameter — a step-by-step guide to precisely measuring every dimension.
Phillips, slotted, hex, socket, Torx, pan, flat, truss — identification features and use cases for every screw head type.
How does computer vision "see" a screw? The deep learning model training process, identification workflow, and how to improve accuracy.
Screws may seem simple, but they are precision engineering components. A single screw's specification includes over a dozen parameters: outer diameter, thread pitch, thread angle, head type, drive type, length, material, surface treatment, and more. Choosing the wrong specification can lead to:
Whether you're a veteran or a beginner, this knowledge will help you make more accurate decisions. Combined with Screw Genius's AI identification tools, screw identification becomes easier than ever.
