Alternative to screw captive idea

Alternative to screw captive idea

Alternative to screw captive idea

(OP)
Hi,

In our assembly section, we use electric nut/screw drivers. Because, they are magnetic, the fasteners are captive in the tool and makes it easier with lesser handling.

Now, I am looking for ideas on similar lines to drive a stainless steel fasteners. Are there any ways to reduce the handling time. Because these easterners aren't magnetic, not the assemblers as to hold the tool, faster and the parts to fasten simultaneously. Its difficult.

Thanks
BT

BluTurtle,

   Most stainless steel fasteners are austenitic stainless, which is not magnetic.  Ferritic stainless is.  I could have that terminology backwards.

   How about some sort of socket head?  Hex socket head cap screws are easy to get.  Robertson or Torx sockets may be available if you look hard enough.

   Would a hexagon head screw work for you?

It has been a while but I have used Mountz (and maybe ASG/Jergens) drivers with vacuum attachment accessories. It will depend on the size of the fastener you are using and what you have available for an air supply.

I could be wrong but I think Torx heads are particularly good for this, as drawoh brings up.  I'm going from memory based on when we were looking at mass producing something at a previous employer and the manufacturing engineer wanted to change screw heads to support this.

RE: Alternative to screw captive idea

You need to look at autofeed screw guns/drivers. You can convert a lot of existing drivers to autofeed. You can get most any fastener collated.  I used Toolbarn as they have a nice cross section of the these tools, but not all as they are others out there

KENAT,

   When I am designing something that requires the assembler to hold on to an inaccessible screw, I specify hex socket head cap screws.  I know that these remain attached to a horizontal driver.   Robertson screws mostly are self-tapping wood screws.  They also remain attached to a horizontal driver, and you can apply lots of torque to them.  They might be available as machine screws in stainless, especially if you need a lot of them.

   Torx screws look to me like they would work, but I have never actually handled one.  I am not sure I own a Torx driver.

drawoh, I only own some because they came with a cheap ratchet driver with separate bits.  Not sure I've ever used them, I think maybe once.

I just remember the manufacturing guy saying how they worked with autofed drivers or something.
