Use Winsted's G8054 Panel Bolts and Clips with Captive Nuts (Pack of 50; Black) to fasten electronics, shelves, or blank panels to your equipment rack.
Each pack includes 50 bolts with fitted washers to avoid scratching your gear. Use clips with captive nuts when rack rails are thinner than average (i.e., to reduce the weight of portable or oversized racks).
Fitted Washers
Fitted washers enable a secure installation while reducing "rack rash." By absorbing applied pressure, they help avoid scratching your electronics and other installed hardware
Clips with Captive Nuts
If your rack rails are of the thinner, lightweight variety, you need clips with captive nuts to hold your bolts in place
