How The Hillman Group Turned Screws Into a Robotics Business

Part of Distributor Playbooks — strategy teardowns of every company on the 2025 MDM Top Distributors lists.

The Hillman Group lands at No. 3 on MDM's 2025 Top Distributors list for fasteners, behind only Fastenal and Würth Industry North America, plus No. 18 in industrial supplies and No. 15 in MRO, on 2024 revenue of $1.5 billion. Those three rankings undersell what Hillman actually is. Read the label and you see a fastener distributor. Read the balance sheet and you find a company that uses screws and bolts as the delivery vehicle for a much stranger, much higher-margin business: robots.

A bolt shop that survived four ownership changes

Max W. Hillman Sr. started the company in 1964 in Cincinnati, selling fasteners to independent hardware stores. His sons Mick and Rick joined in 1969, took over daily operations in 1984, and then watched the business get sold to private equity three separate times in a decade: 2001, 2004, and 2010. CCMP Capital Advisors took the majority stake in 2014, and in 2021 Hillman went public on the Nasdaq under the ticker HLMN through a SPAC merger, according to the company's own history page. Most family-founded distributors that survive that many ownership flips get hollowed out for cash flow along the way. Hillman instead used the private equity years to keep buying: the company has acquired more than 30 businesses, per its mergers and acquisitions page, stacking capabilities in fasteners, hardware, protective gear, and eventually robotics on top of the original bolt bins.

The insight: fasteners buy the shelf, kiosks monetize it

Here is the part that does not show up on Hillman's About page. The company's 2025 10-K and its own investor materials describe a field force of more than 1,100 associates who physically visit roughly 40,000 retail locations, restocking pegs, rebuilding planograms, and keeping the hardware aisle sellable, a service layer wrapped around 111,000-plus fastener and hardware SKUs. That field force and that shelf-space relationship is the real asset. It is also what lets Hillman operate something almost nobody associates with a fastener distributor: a fleet of more than 31,500 self-service key-cutting and engraving kiosks inside the same retail footprint, a business it built by acquiring MinuteKey in 2018 and has kept upgrading with the MinuteKey 3.5 rollout ever since, per Hillman's own release on the deal. That Robotics and Digital Solutions segment pulled in roughly $220 million in 2025 revenue on a razor-and-blade model: Hillman owns the machines, retailers give up the floor space, and Hillman keeps the recurring cut of every key and every engraved dog tag. A commodity fastener business earns the shelf presence; a vending-machine business monetizes it. Few distributors in any vertical have built that second leg, because few have the store-level relationship to place equipment there in the first place.

Buying capability, not just volume

Hillman's acquisition list reads less like a roll-up chasing scale and more like a company filling gaps in what it can put in front of a retail buyer. Koch Industries, picked up in January 2024, brought 2,300 SKUs of rope, twine, and chain and roughly $45 million in revenue, expanding a category Hillman didn't previously own, according to the deal announcement. In April 2026, Hillman bought Campbell Chain & Fittings from Apex Tool Group, adding US-based chain manufacturing and an expected $20 million-plus in incremental 2026 sales, and the same month picked up Delaney Hardware from Sargent and Greenleaf, per the Campbell Chain release. Each deal is small enough to digest inside existing distribution and sales infrastructure rather than requiring a fresh go-to-market. That is the opposite of empire-building for its own sake, and it is a deliberate contrast with acquirers who buy revenue and sort out integration later.

Betting the back office on one building

Hillman's next big move is physical, not financial. In June 2026 it broke ground on a 715,000-square-foot distribution and operations facility in Forest Park, Ohio, built on the former Forest Fair Mall site, consolidating several Cincinnati-area operations into a single hub, according to Hillman's groundbreaking announcement. Consolidating logistics into one campus cuts overhead, but it also concentrates operational risk in one address for a company whose entire model depends on never missing a restock at 40,000 stores. Layered on top is a planned CEO handoff: COO Jon Michael Adinolfi became president and CEO on January 1, 2025, with longtime leader Doug Cahill moving to executive chairman, a transition announced in August 2024 well ahead of the effective date, the kind of orderly succession that public roll-ups don't always manage cleanly.

Hillman is a case study in what happens when a distributor treats its shelf space as the product. The bolts get you in the door; the kiosk in the corner is what pays for the trip.
