Details
Stop hunting for the right socket. This insert holds the complete Tekton SID91211 3/8" drive metric impact set — shallow and deep, 6-point, 6–24mm, 38 pieces, every size labeled.
All 38 pieces — Tekton part numbers
Built to the Tekton SID91211 38-piece set, with pocket sizes taken from calipers on the actual sockets. The shallow sockets stand upright; the deep sockets lie flat in labeled troughs, so the whole set fits a low-profile Packout organizer.
One 3D-printed organizer insert, made to order. It holds the sockets only — the set's rails and rail tray, ratchets, extensions, storage trays and the toolbox are not included.
- Built to match the complete Tekton SID91211 metric impact set — 3/8" drive, shallow and deep, 38 pieces, precision-fit to every size
- Nests top and bottom — stack several on a shelving unit, a workbench, or a deep drawer, wherever works for your shop
- We build in PETG filament. It stands up to a hot truck on a sunny day and shrugs off shop chemicals.
- Engineered, built, and test-fit before it ships. Made in West Virginia.
Good to know
- Insert only — adapters, storage trays, tools and toolbox are not included.
- Visible layer lines are normal. They’re part of how every organizer is printed, and they don’t affect fit or function.
- Color may vary slightly from the photos, due to monitor settings and material batches.
- Some socket slots may extend to the bottom of the organizer, depending on the geometry of the sockets. That’s a normal part of the engineered design, not a defect.
This insert is cut to the exact dimensions of Tekton's SID91211 3/8" metric impact sockets. Sockets from another brand or set may not fit correctly.

Compatibility
Fits natively
Some storage systems need an adapter or spacer tray — see the compatibility details for your exact fit.
Fits with adapter — Packout Organizer
Drops into your deep Packout organizer with or without the spacer tray. If you wish to carry your Packout by its handle, our spacer tray raises the organizer so the lid holds the sockets in place.
Fits with adapter — Packout Drawer
Unlike the lid of a Packout Organizer, the Packout Drawers do not offer the same protection to the sockets from falling out of position if the drawer unit is tipped.
Fits with adapter — Harbor Freight Bauer
Bauer modular drawers (Harbor Freight) use our adapter frame to secure the insert; the sockets themselves are not retained against jarring.
Fits with adapter — Klein MODbox
Klein MODbox drawers use our adapter set to seat the insert.
The Klein MODbox 54500MBX organizer case takes one insert on our one-piece adapter, after its small front and rear ribs are trimmed.
Same mating interface as the adapters — stacks on a shelving unit, a workbench, or a deep drawer.
Always check the label on your storage case or drawer to confirm the exact model number, and compare it against the compatibility chart above. Contact us if you have questions.
