HOW TO USE OUR TOOLS

Make Better Hardware Decisions With Professional Reference Tools

Oushke provides practical calculators, charts, and technical resources to help engineers, buyers, and hardware professionals quickly find reliable information for fastening and component selection.

Designed For Faster And More Accurate Selection

Choosing the correct fastener specifications, torque values, thread dimensions, and component sizes requires accurate reference information. Our online tools simplify complex calculations and provide quick access to commonly used engineering data.

Whether you are selecting bolts for an industrial application, checking thread compatibility, or preparing machining requirements, these resources help reduce manual calculations and improve decision efficiency.

01 Select the right calculator or chart based on your application.
02 Enter your measurements, specifications, or material information.
03 Review the results and apply them to your project requirements.

1. Identify Your Requirement

Determine whether you need torque calculation, thread identification, size conversion, or dimensional reference. Selecting the correct tool ensures more accurate results.

2. Input Technical Data

Enter the required specifications including dimensions, thread standards, torque values, or material parameters. Always use consistent measurement units.

3. Review And Apply Results

Use the calculated values and reference information as a guide for product selection, engineering review, and manufacturing preparation.

Engineering Reference Notice

Our tools are developed for quick reference and preliminary calculations. Actual application results may vary depending on materials, operating conditions, installation methods, and industry requirements. For critical applications, please confirm specifications with professional engineering support.

RESOURCE FRAMEWORK

From Quick Answers to Better Tool Decisions

Oushke Resources organizes practical engineering references, product knowledge and sourcing support into a clear framework. Start with the type of decision you need to make, then move from calculation or lookup to specification and purchasing.

BUILT AROUND REAL TOOL DECISIONS

One Resource Center.
Four Ways to Use It.

A wrench size question and a private-label RFQ are very different tasks. That is why the resource library is organized by purpose rather than placing every reference into one long list.

Use calculators when a value must be determined, charts when a specification needs to be checked, technical references when standards or materials matter, and sourcing resources when a product is moving toward quotation or production.

Choose the resource that matches the decision you are making — not simply the product you are working with.

CALCULATE

Calculate & Convert

Use calculators and converters when you need a numerical result for torque, air consumption, tool sizing, unit conversion, landed cost or other measurable inputs.
