Fleet operators & facility managers.
★★★★★
Fleet runs 38 over-the-road tractors out of Wheeling and we tear into trailer suspensions weekly. Forge ships these same-day from Pittsburgh and the MTR is in the inbox before the box hits the dock. No more sourcing scramble.

★★★★★
We replaced our prior supplier on Grade 8 hardware after a phosphate-coating QA issue. Forge's MTRs come stamped per heat lot, the box weight matches the count, every time. Procurement is finally hands-off on this SKU.

★★★★★
Standing PO at the Hartford DC. Net-30 means we batch invoices monthly instead of cutting checks weekly. Our facilities team loves the consistent box-of-100 packaging — it's a real B2B vendor, not a marketplace listing.
