Type & Shape
           
   Your choices are...         
   Jack Screw       Jack Screws have an appearance similar to male-female Hex standoffs except the male stud is threaded all the way to the body. The studs on jack screws typically are available in multiple lengths. 
   PCB Support (No Hole / Solid Post)       Supports such as circuit board or PCB supports consist of solid post. Often the end has a snap-in, adhesive pad or clip-on fastening mechanism to facilitate quick attachment between two boards between a board and component or board and enclosure. Most PCB supports are made of a plastic material such as nylon. 
   Spacer (Clear Hole / Unthreaded)       Spacers typically have a clear unthreaded hole. 
   Standoff       Standoffs typically have a threaded hole, two threaded holes, two threaded stud or both hole and threaded stud. Standoffs can also have alternate means of mounting or attachment such as adhesive, rivet (Swage standoff), soldering, welding (weld nib), force fit (Knurled), slot mount or edge grip, snap-in, clip-on and other proprietary mounting technologies. 
   Blind Standoff       Blind standoffs have a single internally threaded blind hole, which is closed on one end. They are available in English and metric threads. 
   Female Standoff       Female standoffs have a single internally threaded thru hole or blind hole. They are available in English and metric threads. 
   Female / Female Standoff       Female-female standoffs have two blind holes or internal threads on both ends. They are available in English and metric threads. 
   Hinged / Swivel Standoff       Hinged standoffs or spacers consist of two component connected with a hinge pin to allow the produce to rotate or swivel. 
   Male / Female Standoff       Male-female standoffs have a blind internally threaded hole on one end and external, male threaded stud on the other end. Male-female standoffs are similar to jack screws except the threading on the stud stops a distance from the body. 
   Male / Male (Double Ended)       Male-male standoffs have two external, male threaded studs on each end. 
   Specialty / Other       Other unlisted, specialized, or proprietary type or shape. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Round?       Round spacers and standoffs have a profile with a round cross sectional shape. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Hex?       Hex spacers and standoffs have a profile with a hexagonal or six sided cross sectional shape. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Square?       Square spacers and standoffs have a profile with a square or cross sectional shape with four equal length sides. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Insulating?       Insulated standoffs, spacers or products have high dielectric strength or high electrical resistivity, which allow the insulating standoff or spacer to isolate a board or component. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Mounting
   Mounting       
   Your choices are...         
   Adhesive Mount       Spacer, standoff or support is designed for adhesive bonding to a surface. Bonded spacers or bushing typically have a wide flange, which forms a large bonding surface area.  
   Force Fit / Broaching (Press In)       Standoff, spacer or support held in place by a force fit, broaching or press in process. The end or center of the standoff or spacer has a knurled protrusion sized for a pre-drilled or pre-punched hole in a metal sheet, panel or board. The knurled protrusion is pressed into the panel or sheet. The metal around the hole is slightly deformed, which holds the standoff or support in place. 
   Locking       Spacer, standoff or bushing is designed with a locking mechanism to prevent turning or loosening. The locking option can be an integral lock washer, lock washer features, knurls or teeth. 
   Retaining       Retaining or self-retaining products hold the nut or screw in place to prevent accidental the loss of the nut or screw through vibration. Retaining or self-retaining spacer or standoffs have tabs to hold onto the thread and keep the spacer on the threaded fastener, post or stud. 
   Self-Clinching       Spacer, standoff or support is designed for attachment through a self-clinching process. In the clinching process, the sheet is deformed and pinched by the standoff or spacer.  
   Slot Mount / Edge Grip       Product with a slot in the face or end for edge grip or clamping onto a panel, board, glass sheet, display or plastic sheet. 
   Snap-in / Clip-on       Spacer, standoff or bushing is designed for snap-in or clip-on attachment to a board, component or panel. Snap-in or clip-on fasteners typically have two flexible hook shape teeth, which flex during insertion and then release to hold the standoff or support in place. 
   Swage / Rivet       Spacer, standoff or support is designed for swaging or riveting onto a panel, enclosure surface or board. The standoff or spacer has a thin metal flare, which is deformed to hold the product in place. 
   Threaded       A threaded standoff or support. Threaded spacers are considered standoffs. 
   Specialty / Other       Other unlisted, specialized, or proprietary mounting, fastening or attachment technology. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
