DATA CENTER FASTENING SOLUTIONS
Build Data Center Infrastructure Faster — Without Welding, Rework, or Downtime
From server racks and enclosures to containment and cable pathways and cooling or whitespace construction, Böllhoff fastening systems join thin-gauge and coated sheet metal in seconds — with the strength to survive decades of service cycles.
WHY BÖLLHOFF
145+ Years of Joining Expertise. One Partner for Fastening, Tooling, and Engineering Support.
Böllhoff has been solving fastening challenges since 1877. RIVNUT® — the original blind rivet nut, invented for aircraft in 1936 — has been part of the Böllhoff Group since 2000 and is manufactured in the US in Kendallville, Indiana. Today, as a family-owned group with 44 locations in 26 countries and an in-house test laboratory accredited to DIN EN ISO/IEC 17025, we support the engineers and OEMs building the world's digital infrastructure. We don't just ship fasteners: we help you select, test, tool, and automate the right joining method for your application.
Deployment Timelines Don't Wait for Welding
Every week of rack and enclosure production matters when capacity is pre-sold. Böllhoff joining technologies are built for takt time: RIVCLINCH® clinching creates a finished joint in under one second with no consumables, and RIVNUT® blind rivet nuts install in seconds from one side — no welding, no tapping, no back-side access required. Both are simple to train, easy to automate, and deliver repeatable results across thousands of joints, so your assembly line scales as fast as your customers' compute demand.
Supporting proof points
- Clinch joints set in <1 second
- Up to 32 RIVNUT® settings per minute with battery tooling
- No skilled welding labor required
No Heat. No Sparks. No Damaged Coatings.
Welding warps thin sheet, burns off protective coatings, and has no place near sensitive electronics. Böllhoff joins without heat: RIVCLINCH® cold-forms pre-painted and coated steel, stainless, and aluminum without damaging the surface — with no consumables, no cooling installation, and a fraction of the energy welding demands. ONSERT® bonds threaded studs, standoffs, and cable-management fasteners directly to finished surfaces with a light-curing adhesive — no drilling, no holes, no rework, full load capacity in seconds. Your corrosion protection, airflow design, and clean-room-adjacent environments stay intact.
Threads That Survive Decades of Upgrades
Data center hardware is never installed once. Racks are re-configured, panels removed, equipment refreshed on 3–5 year cycles — all under constant vibration from fans, pumps, and power equipment. RIVNUT® blind rivet nuts put a reusable, load-bearing machine thread into sheet metal as thin as your lightest panel, developed to meet the mechanical requirements of strength class 8.8 (with HRT versions compatible with class 12.9 bolts). RIVNUT® Seal Ring versions provide a tight seal against fluids and gases (per ISO 20653, specification IPX7). Where components must align perfectly across large assemblies — containment panels, doors, façade elements — FLEXITOL® compensates manufacturing tolerances automatically and eliminates warping at assembly.

There's no single right fastener for a data center build. There's a right fastener for each joint. Use this framework as a starting point, then validate with our engineering team:
RIVSET®
RIVNUT®
FLEXITOL®
ONSERT®
RIVCLINCH®
RIVNUT® Blind Rivet Nuts
Strong, Reusable Threads — Installed From One Side, In Seconds
When you can't access the back of a rack rail or cabinet wall, RIVNUT® installs a resilient machine thread blind. Available in steel, stainless steel, and aluminum with a wide range of head styles, sealed and high-strength (HRT) versions — installed with everything from hand tools to fully automated feed systems.
RIVCLINCH® Clinching
Join Sheet Metal With Nothing But the Sheet Metal
RIVCLINCH® cold-forms a permanent, form-fitting interlock between two or more metal layers — no rivets, screws, adhesives, or heat. It joins coated and pre-painted steel, stainless, and aluminum (including dissimilar combinations) without damaging the surface, with joint quality verifiable by simple visual/dimensional inspection — no destructive testing.
ONSERT® Adhesive-Bonded Fasteners
Fasten to Finished Surfaces Without Drilling a Single Hole
ONSERT® bonds threaded studs, bushes, and snap connectors to steel, aluminum, glass, plastics, and composites using a transparent fastener base and light-curing adhesive. Full mechanical load immediately after curing — ideal for adding cable routing, sensors, and mounting points to panels you can't (or won't) penetrate.
RIVSET® Self-Pierce Riveting
High-Strength Multi-Material Joints. No Pre-Drilling.
RIVSET® pierces and joins multiple layers of similar or dissimilar materials — including high-strength steel to aluminum — in one automated stroke. Highly reproducible, dynamically strong, and proven in the world's most demanding high-volume manufacturing environments.
FLEXITOL® Tolerance Compensation
Zero-Gap Assembly, Even When Parts Aren't Perfect
FLEXITOL® automatically compensates axial and radial tolerances as components are bolted together — preventing warping, eliminating shimming, and speeding assembly of doors, panels, and modular structures. Available in metal, hybrid, and plastic systems.
PROVEN IN THE FIELD
