Product catalog summary
Company Overview
Specialinsert® was founded in 1974 by three experienced sales agents in the fasteners industry. The company has expanded to include multiple branches, warehouses, production plants, an R&D office, and testing labs in Italy. It provides advanced fastening solutions for sectors such as metal tubular laminates, mechanical and plastic components, wood, stone, and innovative materials.
Product Overview
Specialinsert® offers a variety of self-clinching inserts for materials like sheet metal, solid wood-metal parts, plastic, and composites. These inserts ensure secure fastening by deforming the material during installation.
Self-Clinching Inserts
Designed to be anchored by pressure into pre-drilled sheets, these inserts are torsion-resistant, capable of bearing high loads, and have reduced dimensions for weight and space efficiency. Installation involves using a punch and counter punch to apply pressure gradually.
Installation Guidelines
  • Ensure the hole is not deburred or countersunk.
  • Adhere to specified drilling diameters, tolerances, and edge distances.
  • Use a traditional press with adjustable pressure.
  • Avoid applying pressure on one side or inclined surfaces.
  • Conduct installation tests for proper use.
Materials and Finishes
Inserts are available in steel and stainless steel, with finishes like white zinc-plating for steel and natural state for stainless steel. They comply with ISO metric thread tolerances and general tolerances according to UNI EN 22768-1.
Product Series
The document details various series of self-clinching fasteners, including threaded studs, nuts, and standoffs, each with specific applications and installation requirements.
Special Products and Services
Specialinsert® offers special products and services, including tools for clinching inserts and collaboration with universities for innovation. The company is associated with UNI and is a member of the Mechanical Orders Commission.
Specifications
Specifications for self-clinching threaded studs and inserts include ISO metric thread tolerance of 6g, with examples of code designation for different types of studs and inserts.
Material and Surface Treatment
Materials include white zinc-plated steel, natural stainless steel, and ferritic stainless steel (available on demand).
Usage
Suitable for sheet metal with hardness up to 80 HRB, 70 HRB, and 90 HRB (on demand).
Installation
Installation requires the stud head to be flush with the sheet metal surface. Preliminary tests are recommended to determine optimal installation conditions.
Performance Data
Includes maximum nut tightening torque, installation pressure, pushout force, torque-out, and pull-thru values for steel and aluminum sheet metals.

INSERTI A PRESSIONE - SELF-CLINCHING FASTENERS INSERTI A PRESSIONE - SELF-CLINCHING INSERTS Sono inserti con una estremità sagomata in modo da permettere mediante pressione di agganciarsi nella lamiera precedentemente forata. In fase di montaggio, il materiale della lamiera viene deformato per la pressione esercitata e si alloggia nell’apposita sede dell’inserto garantendone il fissaggio. Self-clinching inserts have one side shaped in a way that allows them to be anchored by pressure in a previously drilled sheet. During assembly, the material of the sheet, deforming due to the pressure exerted,...
