A lot is for 10 studs or buttons - your choice of length or size, mix and match OK, at the same price. I do have some specials listed in other auctions that are not included at this price, more expensive, but will combine for shipping.

You may combine lengths and sizes from the thousands of Dzus fasteners that I have available in over 100 different sizes. To see the many different sizes and styles of Dzus Fasteners and springs I have available - please click the "SEE OTHER ITEMS" button. I only sell in increments of 10. "Buy it now" the number of lots of 10 from a single auction, and message me the details of the fasteners you want.

Supersonic series Dzus are of a higher quality and tolerance than standard line fasteners. They are sized by the .010" instead of the standard .050". Intended for supersonic pressurized aircraft, but suitable wherever accurate sizing is desired. For example if a A5-40 is too tight you can use an A5T-11 it has .010" more clearance.  They are confusing because the T #s are not relative in different diameters. You need a chart.

Measured from the flat "underhead" surface to the back of the spring after locking.
Each dash number increases the size by .010"

- these are the sizes I have and rough quantities:

A3 1/2-31 (T8)        Q 210

A3 1/2-36 (T13)      Q 20

Some lengths I may have only 50 to 100 in stock - some I have 1000's .

3 1/2  sixteenths" Diameter - shank measures .215"

refered to as A3 1/2 T or A3 1/2 or A35 or A35T or Size 35 is original part # -  confusing?
