Review: Hi quality lock washers - Good amount of different size lock washers that work perfectly
Review: Estás arandelas de bloqueo son muy útiles para zonas donde el tornillo está expuesto a alta vibración lo cual hace que poco a poco y con el tiempo se vaya aflojando, la arandela con el apriete ancla el tornillo a la superficie evitando que se afloje por la vibración. En cuanto a material al ser acero inoxidable se evita un poco más la oxidación. Esté juego viene muy bien surtido y para los que nos gusta hacer labores de reparación en casa tenerlo en nuestro taller es muy útil para cuando se requiera y no perder el día buscando piezas y tener que detener la reparación por falta de arandelas de este tipo.
