Parametric UNC Hexagon Head Screw Generator (STEP, Customizable, CNC & 3D Printing) · 模型 123875
This is a parametric UNC hexagon head screw model generated using an automated CAD system. Unlike fixed models, this screw is not a one-off design — it can be regenerated with different parameters. Specifications of this model: Thread designation: [X] (1/4-20 through 1-8, UNC coarse series) Length: [X] (1/4″ through 1-1/2″, measured under the head) Thread profile: [X] (helical 60° right-hand thread, or plain shank when thread generation is off) Head: Hexagon, hex cap screw series Standard: Based on ASME B1.1 (thread) and ASME B18.2.1 (head) Use cases: Imperial / inch-based assemblies Retrofit and repair of US-standard machinery Machine frames, jigs and fixtures CNC machinery Mechanical design prototyping ⚙️ Generate your own UNC hexagon head screw (any parameters): https://meta-matic. com/en/3d/hexagon-head-screw-unc/ You can freely adjust: Thread designation (1/4-20, 5/16-18, 3/8-16, 7/16-14, 1/2-13, 9/16-12, 5/8-11, 3/4-10, 7/8-9, 1-8) Length (1/4″, 3/8″, 1/2″, 5/8″, 3/4″, 1″, 1-1/4″, 1-1/2″) Thread generation (helical thread or plain shaft) and instantly download a STEP file. Why this matters: Most models here are static. This system allows you to generate exactly what you need. Note: Width across flats and head height follow the ASME B18.2.1 hex cap screw series, not the heavier hex bolt series — the hex bolt series has no 7/16″ or 9/16″ entry, and the cap screw series is the one commonly stocked. Pitch is derived as 25.4 / TPI and all inch values are converted with 1 inch = 25.4 mm exactly, so the STEP file itself is in millimetres. This is a reference implementation based on basic dimensions; tolerances and thread class fits are not applied.
