Unistrut P1010 Cross Reference: B-Line N225, Superstrut A-100 1/2, Power-Strut PS RS 1/2"
Unistrut P1010 cross-references to B-Line N225, Superstrut A-100 1/2, Power-Strut PS RS 1/2" and Haydon N-823. The cited guides list these numbers together as candidate substitutes. That carries no load rating, listing or steel grade: each manufacturer publishes those separately, and they do not travel with a part number.

What a published cross-reference number does and does not cover
A published cross-reference number is one thing only: a number a cited document prints opposite this one, as a candidate substitute in the same catalog slot. We have not independently verified any competitor part's dimensions or interchangeability.
It does not carry design loads, safety factors, steel grade, coating thickness or third-party listings — UL, cUL, FM, seismic. Each manufacturer publishes those independently, and two parts that measure identically can carry different published loads. Finish suffixes differ by brand as well, so order the base number and state the coating in words.
Where a specification names a brand, a substitute is a submittal question, not a purchasing one: send it through as an or equal with the substitute's own load and listing data, and get it accepted in writing before it ships.
Unistrut P1010 — published cross-reference part numbers
P1010 is the 1/2 in.-13 spring nut for 1-5/8 in. deep channel — Channel nut 1/2"-13, with spring (fits P1000/P1100/P2000/P3000). Every value below is copied out of a published cross-reference document; the tag in the source column names it, and the Sources list gives the title, URL and access date.
| Brand | Published cross-reference part number | Source |
|---|---|---|
| B-Line | N225 | [S1], [S2], [S3] |
| Superstrut | A-100 1/2 | [S1], [S2], [S3] |
| Power-Strut | PS RS 1/2" | [S1], [S2], [S3] |
| Haydon | N-823 | [S3] |
No competitor dimensions are published on this page. We hold verified dimensional data for the Unistrut part only, so this table carries part numbers and their sources and stops there.
What to check on a substitute
A cross-reference table gets you a part number. It does not tell you whether the thing in the box lines up with the holes you already have. These are the numbers that decide that for P1010 — 3 checks, each with the Unistrut figure and the catalog page it is printed on. Work through them before the run goes up.
| Measure | Unistrut value | Why | Where the number comes from |
|---|---|---|---|
| Thread | 1/2 in.-13 | Verify it with a 1/2 in.-13 bolt or a thread gauge; a caliper will not settle a thread pitch. The p. 78 table lists P1010 against this thread and the neighbouring part numbers against other threads, which is what makes the thread the first thing to check. | Unistrut® General Engineering Catalog no. 17, p. 78 — printed in the part table |
| Channel depth it is cut for | P1000 / P1100 / P2000 / P3000 | The same 1/2 in.-13 thread in a shallower channel is a different Unistrut number (P4010), and in the deep channel another one again (P5510). A nut that is right in thread and wrong in depth will not turn into the channel. | Unistrut® General Engineering Catalog no. 17, p. 78 — printed in the part table |
| Spring | fitted | This group is the sprung nut. The plain, unsprung nut of the same thread is a separate part number, and it is the substitution that is easiest to miss in a box. | Unistrut® General Engineering Catalog no. 17, p. 78 — printed in the part table |
These are the Unistrut figures, published here so you have something to measure against. They are not a claim about any other manufacturer's part.
What we can quote against this part number
We do not manufacture these parts and we are not Unistrut. We source them. The item we can quote against Unistrut P1010 is Channel nut 1/2"-13, with spring (fits P1000/P1100/P2000/P3000) — a candidate substitute made to order by a contract manufacturer, offered for inquiry, not an original-manufacturer part.
| Dimension | Value | Source |
|---|---|---|
| Thread | 1/2 in.-13 | Unistrut® General Engineering Catalog no. 17, p. 78 — printed in the part table |
| Fits | P1000 / P1100 / P2000 / P3000 channel | Unistrut® General Engineering Catalog no. 17, p. 78 — printed in the part table |
| Spring | fitted | Unistrut® General Engineering Catalog no. 17, p. 78 — printed in the part table |
These are the published Unistrut catalog dimensions we build to, each with the page it is printed on. They are geometry only. No load, torque or listing figure is claimed for our part: none has been tested on it, and a figure published for a Unistrut part is evidence about that part, not about ours.
Every published dimension with the catalog page it is printed on, the finishes, and what to measure on a delivery: P1010 part page.
