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 #14 Wood Screw Pilot Holes

A #14 wood screw has a shaft diameter of 0.242". In softwood (pine, cedar, spruce), drill a 5/32" pilot hole. In hardwood (oak, maple, cherry), use a 11/64" pilot hole to prevent splitting. The clearance hole for a #14 screw is 1/4". Large wood screws, structural connections. Always drill a pilot hole in hardwood to avoid splitting and ensure the screw draws the joint tight.
