What sizes does this cover?

The Socket & Wrench Size pack covers standard metric hex bolts from M3 to M36 and imperial hex bolts from 1/4" to 1-1/2". These are the most common sizes in hardware stores and automotive work.

Are these sizes guaranteed correct?

Sizes are based on ISO and SAE standards for standard hex head bolts and nuts. Actual fasteners vary by manufacturer, grade, and application. Always verify with the fastener when precision matters.

What about Torx, spline, or specialty fasteners?

This tool covers hex head fasteners only. Torx, spline, 12-point, and other drive types are not yet supported.

Can I use the nearest imperial socket on a metric bolt?

In a pinch it may work, but risks rounding the fastener head. Use the correct socket whenever possible. Related values shown are for reference, not substitution.

Will more packs be added?

Yes. Pilot Hole, Tap Drill, and Metric/Imperial conversion packs are planned. The architecture supports new reference sets without changing the app.

5/8" → 16mm Metric

The nearest metric equivalent of 5/8" is 16mm (0.12mm difference).

About 5/8" Conversion

A 5/8" imperial socket or wrench (15.88mm) is closest to 16mm metric, with a difference of 0.12mm. The sizes are close enough for most applications, but always use the correct imperial socket when precision matters. The second-nearest metric size is 15mm (15mm, 0.88mm off). 7/16" SAE bolts. A combination metric and SAE socket set is the best way to handle mixed fasteners without risking damage.
