May fix plastic 1/4-20s
Fixed a 1/4-20 on my digital recorder that had a plastic thread. Had to use a HOT soldering iron to heat it up to fit in but worked great.

quality
The inserts are quality and dimension accurate. i made my own inser tip out of brass rod. The insert heated up even fairly quick. I would recommend a solid stop behind the open hole to control how far its melted thru.

perfetti
Ho acquistato il set di inserti filettati Ruthex #4-40 UNC per i miei progetti di stampa 3D e sono estremamente soddisfatto del risultato. La qualità dei pezzi è eccellente e superano di gran lunga le mie aspettative. Gli inserti sono perfetti per essere inseriti a caldo nelle parti stampate. La loro installazione è rapida e sicura: basta usare un saldatore con una punta adatta e scivolano perfettamente nel foro, creando una filettatura robusta e duratura. Non ho riscontrato problemi di "gioco" o di allentamento una volta raffreddati. La dimensione #4-40 UNC è ideale per una vasta gamma di applicazioni, soprattutto per fissare piccole componenti o per progetti elettronici. La filettatura è precisa e i bulloni si avvitano senza sforzo. Il fatto che vengano forniti in una comoda scatola di plastica riutilizzabile è un ulteriore bonus che aiuta a mantenere tutto in ordine. Questo set da 100 pezzi offre un ottimo rapporto qualità-prezzo e la qualità Made in Germany si percepisce. Li consiglio vivamente a chiunque si occupi di stampa 3D o abbia bisogno di una soluzione solida e affidabile per creare filettature in plastica. Sono diventati un accessorio indispensabile nel mio laboratorio.

Sehr Qualitativ hochwertiges und Robustes Produkt.
1A Produkt, super Qualität, habe es für eine selbstgemachte Mikrofon Halterung aus dem 3D-Drucker gekauft und das Gewinde läuft besser auf dem Mikrofonstativ als so manch ein Gewinde sehr Teurer Veranstaltungstechnik. Inzwischen habe ich die Gewindeeinsätze schon jahrelang im Einsatz und sie funktionieren noch immer super, trotz rauem Umgang.
