New from Elesa: Torque Limiting Wing Knobs

Written by Brian Steeves on . Posted in Captive Fasteners, Products

Here’s another example of another innovative product from Elesa!  CTD wing knobs are used when the applied tightening torque must not exceed a preset value.  These are ideal for applications where over-tightening could result in damage or premature wear of components!

Using these wing knobs is just like any other knob- tighten by turning clockwise as usual.  When the preset torque is reached, you’ll hear a “click”!  To loosen, turn the knob counterclockwise.  No adjustment or calibration is necessary!

Captive Fasteners By Southco

Steeves Agencies carries a wide range of captive fasteners. Why use captive fasteners?
  • They never get lost!  Captive fasteners remain attached to your panel or door whether they’re fastened or not, making them ideal for doors or panels that are frequently removed.
  • They are easy to use!  Some are threaded, others use a “quarter-turn” to latch and unlatch.  It’s never been easier to secure a panel
  • They offer more choices!  Captive fasteners come in a range of varieties- any thread, any stud length, any installation style (press-in, thread in, snap-in), and now, any COLOR!
  When selecting a captive fastener for your project, you should consider these things:
  • The nature of the application:  Is it outdoors, where it might be exposed to harsh weather or corrosive elements?
  • Any access restrictions or code requirements:  if access to your enclosure must be limited (for CSA approved products) then perhaps a tool-operated fastener would be necessary.  We have many options to suit those needs
  • Ease of use:  if finger access is required (no keys or special tools) then you might need a fasteners with a knurled head.
Anything’s possible!  Here are some examples of fasteners we can supply, all from Southco, the world’s leading manufacturer of access hardware!  Call us today for more information.
