Fastener Pro vs Crown Cut Guide

Determine a safe and reliable fastener torque for your application. By selecting your bolt material spec, nut material spec, and set material specs from our comprehensive material database we will evaluate all possible failure modes of the bolt, nut, set material, and joint materials and provide a details stress analysis as well as the recommended torque. Additional features include determination of preload from torque, torque from preload, load analysis, and equivalent angle to turn fastener to achieve desired results. Disclaimer: Bolt torque and preload values are estimates only. Actual requirements depend on material, lubrication, standards, and installation conditions. Verify all values using official engineering documentation and calibrated tools. Developer assumes no liability for use of this information.

Crown Cut Guide helps you calculate crown molding cuts with more confidence and less guesswork. Enter the wall angle, choose the corner type and piece side, set the spring angle, and get clear miter and bevel guidance for the cut ahead. The app is designed for real installation work, where corners are not always perfect and setup details matter. With support for flat/compound and nested/upright methods, single-bevel and dual-bevel saws, custom spring-angle measurement, and vaulted/sloped ceiling transitions, Crown Cut Guide keeps essential crown molding tools in one focused workflow. Key features: • Miter and bevel guidance for crown molding cuts • Flat/compound and nested/upright cutting methods • Single-bevel and dual-bevel saw support • Custom spring-angle measurement from a sample piece • Vaulted/sloped ceiling transition guidance • Clear placement, direction, and keep-side instructions Crown Cut Guide keeps the process simple, practical, and ready to use at the saw. Always verify field measurements and test on scrap before cutting finish material.
