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.

About 3/4" Bolt Torque

A 3/4" hex bolt (Grade 5): reference torque is 266 ft-lbs (361 N·m), with a lubricated estimate of 200 ft-lbs (271 N·m). Standard thread is 10 TPI (UNC coarse) or 16 TPI (UNF fine). Use a 1/2" drive torque wrench. Actual torque depends on thread condition, lubrication, and joint design — always verify with the fastener manufacturer.
