Disclaimer
WhatSocket is a reference utility for guidance only. It is not an official standards body, manufacturer, or engineering authority. The information on this site should be used as a starting point — not as a final answer.
Accuracy & Sources
Reference data on this site is compiled from published fastener charts, manufacturer specifications, and industry standards including ISO, DIN, SAE, ASME, and ASTM references. While we make every effort to ensure accuracy, we cannot guarantee that all values are correct for every application. Fastener specifications vary by manufacturer, grade, material, finish, and application. Values shown are general-purpose reference points, not engineering specifications for a specific use case.
Torque Values
Bolt torque specifications are approximate and depend on many variables including thread condition (dry, oiled, plated), friction coefficient, joint material, bolt grade/class, and tightening method. The torque values shown on this site are general reference values from published charts. They are not a substitute for the fastener manufacturer's torque recommendations, engineering calculations for your specific joint, or proper use of a calibrated torque wrench. Applying incorrect torque can cause joint failure, fastener damage, or safety hazards.
Not a Substitute for Measurement
This site does not replace physically measuring a fastener with calipers, micrometers, or thread gauges. Reference charts identify standard sizes — actual fasteners may differ. When precision matters, always measure the fastener directly and verify against the manufacturer's documentation.
No Warranty & Limitation of Liability
All information is provided "as is" without warranty of any kind, express or implied. WhatSocket, its creators, and contributors are not liable for any damages, injuries, equipment damage, or losses arising from the use of information on this site.

How to Use This Site
- Start here — use WhatSocket to identify the likely size, torque, or drill for your fastener.
- Verify — check the result against the fastener packaging, manufacturer specs, or a printed reference chart.
- Measure — when in doubt, physically measure the fastener with proper tools.
- Ask a professional — for structural, automotive safety, or critical applications, consult a qualified engineer or mechanic.
