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.
