- For
- DIYers and tradespeople checking hardware sizes
- Worth noticing
- The site says each reference page starts with an answer in under 20 words, then provides a table and cited sources.
Field notes
The index breaks the reference into ten hardware sections, with sample lookups ranging from “What 2RS means” to tire-size comparisons and bolt patterns. SizeSheet says its values come from manufacturer charts and published standards, cited at the bottom of each page, and cautions readers to check exact-part specifications. Its torque note specifically limits the figures to general guidance for clean, unplated steel.
