Item Size Lookup
Type a size, gauge, screw or drill designation, nail size, pipe size, shoe size, or caliber into the box below and see everything else — across wire gauges, drill bits, pipe schedules, fasteners, firearms, medical devices, electronics, and hundreds of other real-world standards — that lines up at that exact dimension.
A note on accuracy: every entry is pulled from a real, cited standard or manufacturer spec, but this is one engineer’s reference chart, not a certified document. Verify any dimension against the actual governing spec before relying on it for a purchase, a fit-up, or anything safety-critical.

Sliders cover 0.00001in (0.254µm) to 24in on a logarithmic scale, dragged live. For anything finer than that (viruses, molecules, subatomic-scale records), type it into the search box above instead.
Columns to show
Typing a search auto-checks only the columns that actually have data for the matching rows, so the table isn't full of empty cells -- clear the search box or click "View All Rows" to go back to every column. Individually checking or unchecking a column here also checks/unchecks its matching field below in "Filter rows by field", so picking a column shows the rows that actually have it (Select All/Deselect All don't cascade this way).
Filter rows by field
Only show rows where at least one checked field has a value here -- e.g. check "Cap Screw" to see only rows with an available screw size. Checking a field here also jumps the Size range sliders above to that field's own real min/max size and shows those rows immediately, and checks the matching column above in "Columns to show" -- clearing every checked field resets the sliders back to the full range.
