Escoger la punta de destornillador equivocada puede a veces ser la diferencia entre una buena reparación y un problema. Si sigues los consejos de esta guía para identificar correctamente tus puntas y usarlas, evitarás desgastar la cabeza de tus tornillos de manera irremediable.

Si aún así sigues teniendo problemas, echa un vistazo a esta fantástica guía con consejos para usar el destornillador.

    • Las puntas incluidas en los kits de puntas de iFixit tienen prefijos que indican el tipo de cabeza. Estos prefijos suelen estar seguidos de un número que indica el tamaño de la punta. Por ejemplo:

    • PH2 (Phillips #2): Una punta Phillips (o de estrella) grande.

    • PH0 (Phillips #0): Una punta Phillips (o de estrella) mediana.

    • PH000' (Phillips #000): Una punta Phillips (o de estrella) pequeña.

    • Escoge el tamaño de punta que se ajusta a la cabeza de tu tornillo. Una punta demasiado grande no entrará correctamente, y acabarás desgastando el orificio de la cabeza.

    • Si tienes problemas identificando la punta que necesitas en tu kit de herramientas, usa esta lista de referencia.

    • Forma de la punta, seguido de su nombre propio.

    • Tamaño de la punta.

    • Si no hay un prefijo en tu punta, simplemente usa el nombre propio completo y el tamaño para buscar tu punta. Por ejemplo: "Usa una punta plana de 1.5 mm para quitar los dos tornillos de 5 mm de la carcasa"

  3. Cómo elegir la punta de destornillador adecuada, PH vs JIS: paso 3, imagen 1 de 2 Cómo elegir la punta de destornillador adecuada, PH vs JIS: paso 3, imagen 2 de 2
    • Las puntas con el prefijo "J" y "PH" a veces se confunden entre ellas. Que no te engañe su aspecto similar, ya que son bastante diferentes.

    • Los tornillos Phillips (PH) están diseñados para expulsar a un destornillador Phillips si le aplica demasiada fuerza de giro. Esto evitará que dañes los tornillos, los destornilladores o las puntas.

    • Los tornillos "Japanese Industrial Standard"(J) (industriales estándar de Japón, o JIS) no expulsan el destornillador, y tienen bordes de 90 º.

    • Las puntas J (JIS) y PH (Phillips) no siempre se pueden intercambiar. Como ya se ha explicado, no tienen propiedades físicas iguales.

    which is which? why not tag each with a label?

    Japanese Industrial Standard (J) screws do not provide a cam-out option, and have 90 degree corners

    Does a PH bit also fit into a J screw?

    Alberto - Contestar

    Hiya, Alberto! Great question. Smaller screws found in electronics aren’t particularly durable, and using a Phillips screwdriver on a Japanese Industrial Standard screw head (or vice versa) can lead to some pretty major problems. I highly recommend using the proper screwdriver or bit to avoid stripping screws.

    Which one should I get in America for iPhone and laptop type repairs , PH or J?

    eliyahu Stein - Contestar

    According to JIS and ISO standard, both recess dimension seem to be the same, having a rounded corner between two flats. I think, the recess without rounded corners (as right drawing) is a recess of CIPA (older JCIS) standard. According to CIPA, the edge between two flats is R0.06mm rounded shape, which seems to be neary sharp edge. Anyway, CIPA is a Japanese Standard and used mainly for the screws of Japanese electrical instruments.

    I have two Phillips heads, one is labelled PH.2, the other labeled SH.0.

    The second one has a very snub nose, which is what I need for the screws I need to work on. The more pointed PH one is too loose as the point doesn't allow it to fully seat into the screw head.

    A seemingly identical snub-nosed one from another set is labelled: CR-V3#, and another seeming clone as ACR-2..

    I'm having a bit of confusion on how to buy another screw bit like I need.

Excellent guide. could not figure out the difference by looking.

Lawrence Steinheuer-Turner - Contestar

It would be clearer if the displayed drawing of each bit actually said J-bit or PH-bit, and because both have 90 degree corners, maybe change the J-bit description to “have 90 degree square inside corners“ and include in the PH description “have 90 degree rounded inside corners.

Otherwise, with interpretation, your article helped me.

what size hex shaft do these smaller bits have?. i have an electric precision screw driver, for electronics. i go through the PH1 bits very quickly. i can NOT find them for sale anywhere on earth. does anybody know where to purchase these things?? and/or tell me how i should word the query. all im getting is 1/4 hex shaft results. very frustrating

In the picture on the top of the page the bits with a 90° corner are marked as Phillips heads, the ones with the rounded corners are markes as JIS heads. But it seems to be the other way, as mentioned in Step 3 of this instruction, and also according to other pages like

Sharp eye, Andreas! Thanks for catching that. We’ve updated the image at the top of the guide with the correct labels.

Marty Rippens -

i have just bought an ifixit kit, has some ph and j bits. I’ve looked at them under a microscope, compared angles, tried them on screws... i have found no difference whatsoever, they seem to be identical. What gives?

Victor Titov - Contestar

Hi @deepsoic, that’s a pretty interesting find you’ve made! Send an email over to our customer service team at and they’ll help you get this issue sorted.

The label indicating the drivers on the Mako 64-bit driver set is almost impossible to read (embossed black-on-black). You can print a better one from the diagram on the catalog page. See

I got this set as a gift and I’m very disappointed it doesn’t include larger Phillips head bits. The largest in this set is too small for a lot of the screwheads on my electronics, especially since I’ve never seen some of these screwheads in my entire life. Do you have any larger Phillips bits for sale?

Matt - Contestar

Hi, Matt! Sorry to hear that your current kit doesn't meet your needs. We do have a larger 1/4" driver kit that goes up to PH #3 (Mahi).
