Details
Your Tekton SKT15311 in one deep Packout. Tekton's 73-piece SKT15311 is two Tekton sets combined: the SKT15101 SAE set and the SHD91211 metric set, plus a breaker bar. This set gives you our organizer insert for each one and a 14mm spacer, so both organizers stack in a single Milwaukee Packout 48-22-8430 or 48-22-8435. Every size is labeled. Not included: the SKT15311's 18" breaker bar. It has no slot in this set; the organizers hold the other 72 pieces. Have a low-profile Packout 48-22-8431 instead? Our original SKT15311 pair (two half-width inserts that sit side by side, no spacer) is cut for that box.
All 72 pieces — Tekton part numbers
In each organizer the shallow sockets stand upright and the deep sockets lie flat in labeled troughs. The SAE organizer also has its own slots for the ratchet, both extensions and the universal joint. The spacer and the two organizers stack in any order: under the stack it lifts the organizers so the lid holds the sockets, and on top its base holds the sockets in the organizer below. The spacer is also an open storage tray for flat parts that ride in the box.
Three 3D-printed pieces, made to order: the SAE organizer insert, the metric organizer insert and the 14mm spacer and storage tray. The sockets, ratchet, extensions, universal joint, breaker bar, Tekton's own storage case and the toolbox are not included.
- Built to match the complete Tekton SKT15311 set (SKT15101 SAE + SHD91211 metric), 3/8" drive, shallow and deep, plus the ratchet, extensions and universal joint: 72 pieces, precision-fit to every piece
- Fits one Milwaukee Packout 48-22-8430 or 48-22-8435, and the three pieces stack in any order
- Nests top and bottom, so the pieces also stack on a shelving unit, a workbench, or in a deep drawer
- 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
- Organizer inserts and storage tray only — adapters, 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.
These inserts are cut to the exact dimensions of Tekton's SKT15101 SAE and SHD91211 metric sets, the two halves of the SKT15311. Sockets and tools 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 — 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.
