Frequently Asked Questions

Screw Genius is an AI-powered screw identification tool platform. Simply take a photo of a screw or engineering drawing, and the AI can identify the screw's head type, thread pitch, outer diameter, length, and other key specifications within seconds. Beyond identification, it also offers professional engineering tools including weight estimation, blank calculation, and cost quotation.

We use advanced computer vision models to analyze screw photos or engineering drawings. The AI identifies the screw's visual features (head type, drive type, thread pattern), then cross-references a screw specification database to determine the most likely parameters. The system combines deep learning with industry expertise, continuously optimizing identification accuracy.

Under good lighting and with clear photos, AI accuracy for common screw specifications reaches 85-95%. Factors affecting accuracy include photo clarity, lighting conditions, screw angle, and whether the screw follows standard specifications. We recommend using AI results as an initial assessment, supplemented by physical measurement tools for final confirmation.

Currently supported screw types include: metric screws (M series), imperial screws (UNC/UNF), self-tapping screws, machine screws, hex bolts, socket head cap screws, Phillips screws, slotted screws, and hundreds more common specifications. Our AI model continuously learns new screw types, expanding coverage over time.

The Free plan provides 5 AI identifications per month and basic engineering tools (torque analysis, die life estimation, etc.). The Pro plan at $9.9/month offers 300 AI identifications and unlocks batch drawing analysis, screw weight estimation, blank diameter calculation, reverse specification lookup, and more advanced features. The Enterprise plan at $49/month provides 2,000 identifications and priority support. See Pricing for details.

Yes. Uploaded photos are only used for AI identification analysis and are not permanently stored on our servers after processing. Account data is securely stored via Supabase, and payment information is processed by Paddle (an authorized payment processor) — we never access your credit card information. See our Privacy Policy for details.

Screw Genius is a cloud-based SaaS tool, and AI identification requires an internet connection. However, some engineering calculation tools (such as torque analysis and die life estimation) can still be used offline, as the calculation logic runs locally.

Screw Genius supports 9 languages: Traditional Chinese, Simplified Chinese, English, Vietnamese, German, Japanese, Hindi, Thai, and Arabic. The interface automatically detects your browser language settings, and you can also switch manually in the settings page.

You can cancel your subscription anytime from the settings page. After cancellation, you can continue using all paid features until the end of the current billing period. New subscribers enjoy a 14-day refund guarantee. See our Refund Policy for details.

You can send an email to service@screwgenius.com via our Contact Us page. We typically respond within 48 hours. Pro and Enterprise users enjoy priority support.

Tips: (1) Shoot in well-lit conditions; (2) Make the screw fill most of the frame; (3) Take one photo from the front and one from the side; (4) Avoid glare or blur; (5) For engineering drawings, ensure the drawing is clear and text is legible.

The Pro plan supports uploading up to 5 drawings for parallel analysis at once. The Enterprise plan supports up to 15. Ideal for high-volume quotation workflows at screw factories and trading companies, saving 90% of manual input time.

Yes. The Vision Memory feature records your correction habits for AI identification results. Next time a similar drawing is analyzed, it automatically applies your preferences — the more you use it, the more accurate it becomes. Memory is completely private to your account and not shared with any other users (including industry competitors).

Reverse lookup lets you input a blank (wire) diameter, and the system automatically cross-references all standard screw specifications, sorted by deviation from smallest to largest. It's ideal for determining which screws can be manufactured from existing stock materials, avoiding unnecessary new material purchases.

The system includes built-in coating thickness data for common plating types (Fe/Zn 5-12μm, electroless nickel, hot-dip galvanizing, Dacromet, Geomet). It automatically calculates the plating impact on pitch diameter (formula: ΔD ≈ 4 × coating thickness) and subtracts it from the recommended diameter to ensure the finished product meets specifications after plating.

Die life is calculated based on screw dimensions, material (C1022/SCM435/SUS304, etc.), heat treatment grade, die material (DC53/SKH51, etc.), and whether nitriding treatment is applied. The algorithm combines the founder's 10+ years of hands-on thread rolling die R&D experience, with estimation accuracy within practical production ranges.
