FILTEC® - Helical thread insert

Product catalog summary
Company Overview
Specialinsert® was established in 1974 by three experienced sales agents in the fasteners industry. The company has grown to include multiple branches, warehouses, production plants, an R&D office, and testing labs in Italy. It offers advanced fastening solutions for sectors such as metal, mechanical, plastic, wood, stone, and innovative materials.
Product Introduction: FILTEC® Helical Thread Inserts
FILTEC® helical thread inserts are used for high-quality assemblies across various industries. Made from wire with a lozenge-shaped section, they create two precision concentric threads and include a removable tang for mounting.
Materials and Applications
These inserts are available in materials like stainless steel, phosphor bronze, Inconel X 750, and Nimonic 90, offering resistance to acids, corrosion, high temperatures, and non-magnetic properties.
Uses and Advantages
Designed for reinforcement in tapping, FILTEC® inserts are used in original, repair, or modification applications. They ensure equal load distribution, reduce material and size, resist wear and corrosion, and simplify lock systems with a self-locking feature.
Self-Locking Insert
The self-locking insert prevents unscrewing due to dynamic stress, vibrations, or heat loads, meeting ISO 2320 standards and identifiable by their red color.
Specifications
Specifications include screw sizes and unscrewing times, based on ISO 2320 standards for steel screws of grade 8.8.
Helical Thread Inserts
Installation is easy with manual, semi-automatic, or automatic tools, emphasizing proper axial alignment with the threaded seat.
Boring and Tapping
Boring requires a hole larger than the nominal screw diameter with a countersunk angle of 120° or less. Tapping uses a FILTEC® tap, checked with a go/no-go gauge.
Fitting Method
Inserts are fitted using manual or powered tools, screwed down to 1/4 to 1/2 a turn below the fitting plane.
Breaking of the Tang
The tang is broken using a FILTEC® punch.
Production Program
Includes threading standards like Metric ISO, UNC/UNJC, UNF/UNJF, GAS - BSP, BSW, and BSF, with options for standard and self-locking threads.
Standardization
Standard inserts do not conform to DIN 8140 but can be produced to meet DIN 8140 and EN 2944 upon request.
Designation
Details on code numbers, execution methods, materials, and surface coatings are provided.
Tables and Data
Extensive tables detail screw dimensions, bore sizes, and insert lengths, with ordering codes.

FILETTO RIPORTATO ELICOIDALE - HELICAL THREAD INSERTS - FILTEC® UN INSERTO DI QUALITÀ Il filetto a riportare FILTEC®, Standard o Frenato, è utilizzato in tutti i settori dell’ industria ed è elemento indispensabile per ottenere una grande tenuta negli assemblaggi di alta qualità. Il filetto FILTEC® nasce da un filo con sezione a losanga che genera due filettature concentriche di precisione, una interna ed una esterna. Il filetto FILTEC® termina ad una estremità con un codulo chiamato trascinatore. Il trascinatore serve per il montaggio del filetto e, dopo l’inserimento, se necessario, viene staccato...

FILETTO RIPORTATO ELICOIDALE - HELICAL THREAD INSERTS - FILTEC® FILETTO AUTOFRENANTE FILTEC® ll filetto autofrenante a riportare FILTEC® corrisponde in tutto al filetto a riportare standard. La sua caratteristica sta nel frenaggio della vite. Il frenaggio della vite si ottiene per la deformazione poligonale di una o più spire del filetto autofrenante. Questa deformazione genera una forte aderenza sui fianchi della filettatura della vite ed elimina gli effetti di svitamento provocato da sollecitazioni dinamiche, da vibrazioni, o da carichi termici. Il frenaggio della vite evita l’impiego di controdadi,...
