The light-bar assembly put quarter-twenty and M5 hardware in the same project. This SAE and metric set is part of my purchased threading kit for keeping those systems distinct.
I bought OMT SAE and Metric Tap and Die Set as part of my camper van equipment.
The light-bar assembly put quarter-twenty and M5 hardware in the same project. This SAE and metric set is part of my purchased threading kit for keeping those systems distinct.
Keeping Inch and Metric Thread Coverage Visible
The light-bar build used quarter-twenty hardware at the rack.
I used M5 hardware at the smaller added profile.
My threading purchases included an OMT set covering SAE and metric sizes.
The profiles and joint hardware during my roof-mount assembly.The drilled connectors and fasteners joining my added extrusion to the roof rack.
My Takeaway from This Job
The two hardware families in the roof project make thread coverage a useful organizing choice. All three sets below cover inch and metric tools; the included sizes and the holder format distinguish the packages, including ratcheting holders in the 82812 set.
Compare thread coverage and the turning-holder format separately.

Taps, dies and holders
An SAE and metric tap-and-die case puts two thread systems beside each other. The OMT set includes internal-thread taps, external-thread dies and hand holders. For repair work, identify both diameter and pitch before working on an existing fastener or threaded hole. Similar-looking pieces can belong to different systems. Keep the selected tool with the matching fastener while working, then return it to the marked case position. That organization is useful when a van repair involves hardware from several different suppliers.
Diameter does not fully identify a thread. Pitch must also match, and SAE and metric thread systems should remain distinct during identification and repair.

Two Alternatives to Compare
Both GEARWRENCH sets combine SAE and metric threading tools. The 82812 and 3887 differ in assortment and holder format, so the thread sizes drive the comparison.
This GEARWRENCH set combines SAE and metric threading tools in a fitted case. Ratcheting holders turn the taps and dies during internal or external threading work.
This GEARWRENCH set groups inch and metric taps and dies with turning tools. The case separates the thread sizes and accessories into labeled positions.
