Captive screws are used where it is important for the screw to be retained where a regular fastening could be taken out fully and lost either inside existing equipment, or on the floor and not found compromsing the safety of the euipment as a whole. A wide variety of controls and PC parts for electrical engineers including Controls, Powers, PC parts and more. Our captive screws are available n stainless steel (AISI 303 (A2) and 316 (A4) series), titanium, aluminium and more. g. P0168 - see bottom right diagram in the application images) or retaining flange (for thin panels; e. Browse industrial materials ranging from heat insulating plates, sponges, to metal and plastic materials in different sizes to meet your various applications.
M3 x 12mm Knurled Thin Thumb Screws (DIN 653) - A1 Stainless
Mn for a number n means that the diameter of the screw, projected onto the transverse plane, is n milimeters - including the threading.A wide variety of standard and configurable components for factory automation engineers in industries such as automotive, semiconductor, packaging, medical and many more. The 'knurled' feature of the head makes this type of screw ideal for use where conditions can be challenging such as food preparation or clean room operations.

Our thin head captive thumb screws are generally produced in AISI 303 and 316 series stainless steel. Generally used in timber to timber and timber to metal construction, these bolts incorporate a square neck to grip the hole in the timber when fitting, and therefore negates the need for any drive recess to be included on top of the head. UNBRAKO® branded and manufactured to be stronger than the other size for size high tensile versions. A wide variety of wiring parts for connecting and protecting control and PC parts including Connectors, Cables, Electric Wires, Crimping Terminals and more.

I recently came across the Open Source Optics collection by jpearce (it's really great, you should check it out: http://www. Also available to purchase online are threaded washers and retaining flanges for captive screw installation on thin or non-threaded panels.
Special thin diameter slotted head captive thumb screws in stainless steel (AISI 303 or 316 series) and titanium. Generally, captive screws have a smooth (non-threaded) shoulder/shank that has a smaller diameter than the threaded end portion. A good selection of accessories such as screws, bolts, washers and nuts that you may need for your daily engineering usage.
Knurled Thumb Screws DIN 464 Black Oxide M3 to M10 - Boneham
Also available are Knurled Screws or Nuts made from either Steel, with a tensile strength class of 5.Most importantly, 'x', the space between the two threaded areas in the application should be greater than the thread length (l 2) of the captive screw. A single phase nickel-copper alloy with excellent properties at both very high and very low temperatures. It can withstand acidic and marine environments and is more expensive than 303/304 series stainless steel.
