Who We Sell To
We sell to the shop that uses the part, not the shop that resells it
The big master distributors move product through a channel — you buy from a distributor, who buys from them. That works until you need forty pieces of something odd on Thursday. We stock deep and sell direct: to OEMs, job shops, fabricators and maintenance departments.
OEM & Assembly
Production lines running a standing bill of material
Released against a blanket, packed to your bin quantities and labeled with your part number. We hold the safety stock so you don't carry it.
Contract & Job Shops
Short runs where the print changes every week
Mixed grades, small counts, no minimum order penalty. Most job shop orders leave the same afternoon they're placed.
Maintenance & MRO
Plant crews who need it before second shift
Will-call at the Vandalia dock until 5:00, and next-day truck delivery inside a 150-mile radius of Dayton.
Fabrication & Steel
Structural work with certs attached
F3125 grade A325 bolts with compatible A563 DH nuts and F436 washers. Mill test reports pulled at shipment — each component traced to its own heat or production lot.
Paperwork
Certs, traceability and country of origin — without a phone call
Every graded and structural lot stays traceable to its manufacturer's heat or production lot. If your quality system needs the documentation, it ships in the box with the parts.
- ISO 9001:2015 certified, single facility, audited annually
- Mill test reports and certificates of conformance on request
- Heat-lot traceability on all graded and structural product
- Domestic and DFARS-compliant lines stocked separately
- Country of origin stated on every quotation and packing list
- PPAP documentation for production release programs
