The terms that apply to using HexCapScrews.com and its reference content and tools.
Last updated: September 2026
Everything on HexCapScrews.com — grade and dimensional data, mechanical and chemical properties, spec sheets, charts, and calculators — is provided for general reference and educational purposes. It is a convenience, not a controlling document.
Values here are transcribed from, or derived from, published industry standards (such as SAE J429; ASTM A307, A449, and A354; and ASME B18.2.1). Standards are revised over time, and transcription can introduce error. Before you specify, purchase, install, or otherwise rely on any value, confirm it against the current published standard itself and against your own project drawings, engineering documents, and supplier data.
This site does not provide engineering, design, or professional advice, and using it does not create any professional relationship. Fastener selection for load-bearing, safety-critical, or code-governed applications should be reviewed by a qualified engineer familiar with your specific application.
Any calculator on this site returns theoretical results based on nominal dimensions and idealized geometry. Results exclude plating, coatings, chamfers, manufacturing tolerances, and other real-world variation, and may differ from a specific supplier's product. Verify against actual product data before quoting, ordering, or relying on a result.
The content and tools are provided “as is” and “as available,” without warranties of any kind, express or implied, including any warranty of accuracy, completeness, merchantability, or fitness for a particular purpose.
To the fullest extent permitted by law, HexCapScrews.com and its operator are not liable for any loss, damage, or cost arising out of or connected to the use of, or reliance on, this site or its content or tools, including errors or omissions in the data.
The content, tools, and these terms may be updated or changed at any time without notice. Continued use of the site constitutes acceptance of the terms then in effect.
This is an independent reference, and accuracy matters. If you spot an error, corrections are genuinely welcome — please reach out so it can be fixed.
