Nuts & Bolts

Quick reference for screw dimensions and drill sizes

Features & Capabilities

Nuts & Bolts is a handy Chrome extension designed for quick and easy reference of screw dimensions and drill sizes. It covers a wide range of screw sizes, including standard sizes from #0 to 1" and metric sizes from M1.4 to M24. The extension provides critical information such as screw diameters, screw head dimensions, tap drill sizes, and clearance hole specifications. Users can smoothly cycle through different sizes and screw types or jump instantly to the desired size by tapping any dimension.

The free version includes comprehensive data for screw diameters, tap drill sizes, clearance holes, and head dimensions for pan and button head screws. Upgrading to the PRO version unlocks additional screw head dimensions for types like socket head cap screws, round, flat, hex, binder, fillister, and truss screws. This makes Nuts & Bolts an essential tool for engineers, hobbyists, and professionals needing quick and reliable screw size references directly in their browser.

User Reviews

Users find the app useful for displaying bolt information clearly and better than charts. However, many complain about the limited selection of bolts and screws, absence of nuts despite the name, app crashes after updates, and poor support for newer Android versions. The free version is too limited, making the pro version necessary but difficult to evaluate. Overall, the app needs updates and broader content to meet user expectations.
Pros
  • Clear and good display of information.
  • App is better than a physical chart for bolt sizes.
  • Contains useful information for bolts.
  • Has both metric and inch sizes (though limited).
Cons
  • Limited selection of screws and bolts; lacks obscure or all varieties.
  • No information or inclusion of nuts despite app name.
  • Crashes immediately after update claiming error reading screw sizes.
  • Free version is very limited; requires pro version for full features and no way to evaluate pro version worth.
  • App appears outdated and possibly developed for earlier Android versions, causing compatibility issues.

Only a very limited selection of screws. Doesn't have any information about obscure ones.
