Specialinsert

What Specialinsert does

Specialinsert Srl is a privately held Italian manufacturer of mechanical fastening systems (fasteners), founded in 1974 and headquartered in Turin with branch offices in Milan and Maerne di Martellago (VE). The company designs, produces, and commercializes engineered fastening solutions for industrial B2B customers, including threaded inserts, threaded bushes, self-clinching inserts, blind rivets, nuts, studs, screws, wire thread inserts, and specialized fasteners for plastics, wood, composites, honeycomb-sandwich panels, and stone/marble materials.

Its product portfolio is anchored by a set of proprietary, trademarked technologies: KEEP-NUT® (self-anchoring threaded inserts for stone/porcelain, ETA-certified), MASTER-PLATE® (bonded studs/nuts/bushes for composites and prefabricated assemblies), FAST-CON® (patented quick-snap fastening), Deform-Nut® (deformable inserts for carbon fiber and layered composites), and Float-Nut (floating nuts with tolerance compensation for high-end automotive). Specialinsert holds IATF 16949:2016 automotive quality certification and ICIM AUTO 2024 certification, and operates an internal testing laboratory to validate fasteners across metals, composites, plastics, wood, and stone.

Commercially, Specialinsert runs an enterprise field sales motion with technical sales assistance and co-design/customization, supported by a product website with downloadable CAD files, datasheets, and a 'Techub' technical resource. It sells to manufacturers in automotive (supercars, hypercars, EVs, including Dallara), aerospace, railway, construction and architecture (stone facades, ventilated facades), modular/prefabricated construction, furniture, and nautical/maritime. Pricing is quote-based on specifications, materials, and volume with no public price list, and the company emphasizes Total Cost of Ownership over unit price — arguing the fastener itself represents only ~15% of lifecycle cost while logistics, assembly time, quality control, and maintenance comprise the balance. Specialhighlight post-2026 EU procurement is the Carbon Border Adjustment Mechanism, which Specialinsert uses to differentiate its Italian-made products from imported (notably Asian) fastener alternatives.
