AI Screw Identifier
Identify any screw or fastener instantly with AI. Upload photos of screws from any angleāget type, size, drive pattern, thread specifications, material composition, and compatible driver information in seconds. Perfect for DIY enthusiasts, contractors, and hardware professionals.
How to Use This AI Screw Identifier
Upload a photo of any screw or fastener, or describe it in the text box. The AI analyzes head type, drive pattern, thread configuration, and physical characteristics to identify the specific screw type. You'll get size specifications, material information, compatible drivers, and common applications instantly.
Best Photo Tips
Photograph screws from above showing the head and drive pattern clearly, and from the side showing thread pitch and length. Good lighting and sharp focus on the head are essential.
Describe Details
Include head shape, drive type, approximate length and diameter, thread pattern, material (if known), finish color, and any markings on the head for accurate identification.
Get Specifications
After identification, receive detailed specifications including exact size, thread pitch, material grade, compatible drivers, typical applications, and strength ratings.
Common Screw Types Identified
- Wood Screws: Flathead, roundhead, oval head with Phillips, square, or slotted drives
- Machine Screws: Pan head, button head, socket head cap screws with metric or imperial threads
- Self-Tapping Screws: Sheet metal screws, self-drilling screws with sharp threads
- Drywall Screws: Coarse thread, fine thread, bugle head Phillips drive screws
- Deck Screws: Exterior-rated, coated, star drive or square drive fasteners
- Lag Screws: Heavy-duty hex head or square head wood screws
- Set Screws: Headless screws with hex socket, used for securing components
- Security Screws: Tamper-resistant drives like Torx, tri-wing, or one-way screws
Why Identify Screws?
Understanding screw specifications ensures project success, proper installation, and safety:
- Replacement accuracy: Find exact matches when replacing lost or damaged screws
- Tool selection: Determine which driver or bit you need before starting work
- Material compatibility: Choose screws rated for your specific application and materials
- Load requirements: Understand strength ratings for structural or safety-critical applications
- Inventory management: Organize hardware collections with accurate labeling and categorization
Understanding AI Screw Recognition Technology
Our AI screw identifier uses computer vision trained on extensive fastener databases. The system analyzes:
- Head shape: Flat, pan, round, oval, button, hex, socket, truss, or specialty head designs
- Drive pattern: Slotted, Phillips, Pozidriv, square (Robertson), hex, Torx, or security drives
- Thread configuration: Coarse vs. fine threads, pitch measurement, thread angle, and root diameter
- Physical dimensions: Length, major diameter, minor diameter, head diameter, and drive size
- Material indicators: Color, finish, coating (zinc, black oxide, stainless), and surface texture
The AI compares your fastener against comprehensive hardware databases to provide accurate identification and specifications.
Drive Types and Applications
Phillips Drive is the most common cross-shaped drive, designed to cam out under high torque to prevent over-tightening. The AI identifies PH1, PH2, PH3 sizes and recommends proper driver bits.
Square Drive (Robertson) provides excellent torque transfer with minimal cam-out, popular in Canada and for deck screws. The AI recognizes sizes from #1 to #3.
Torx/Star Drive offers superior torque transmission and reduced wear, commonly used in automotive and electronics. The AI identifies T-sizes from T10 to T50.
Hex Socket allows high torque application in recessed applications, common in machinery and furniture assembly. The AI specifies Allen key sizes in metric and imperial.
Thread Types and Materials
Coarse Threads work best in soft materials like wood and plastic, providing good grip and faster installation. The AI identifies thread pitch and recommends pilot hole sizes.
Fine Threads suit harder materials and provide better holding power in metal applications. The AI specifies thread count per inch or metric pitch.
Material Grades affect strength and corrosion resistance. The AI identifies steel grades (Grade 2, 5, 8), stainless steel types (304, 316), brass, aluminum, and specialized coatings for different environments.
Understanding thread and material specifications prevents stripping, ensures proper strength, and extends fastener life in various conditions.
