Bolts, Nuts, Spacers, Clamps & Washers
This page last updated 12/13/13
Nylon nuts, bolts, washers and clamps are ideal for mounting High Q coils, ferrite rods, toroids, and capacitors; and, nylon spacers (rods) work well as shaft extenders to greatly reduce “hand” capacitance of panel mount controls, such as the XS-365 air variable capacitor.
We recommend drilling and tapping 4-40 holes in each ½-inch spacer – with 0.257 inner-diameter hole - to accommodate ¼-inch spacer(s) for coupling to a capacitor or potentiometer ¼-inch shaft. Use a #43 drill bit for the hole and a #4-40NC tap with T-handle. These bits/taps are available at ACE Hardware or other stores. 10-32 or 1/4-20 bolts work well for mounting coils.
The clamps are ideal for holding 3/8- or 1/2-inch ferrite rods, as shown at right. Use 10-32 or 6-32 nylon screws & nuts to secure the clamp. The large washers accommodate mounting of FT-82-61 or FT-87A-J toroids. The 1/4-20 screws/nuts listed fit the large washers.
