Hammond 142150 is a 50-piece rack mounting hardware kit containing 50 nickel-plated 10-32 rack screws and 50 nickel-plated steel cup finishing washers, supplied in a clamshell package. It is intended for IT, AV, broadcast and industrial installers mounting equipment to standard 10-32 threaded rack rails, and for OEMs and maintenance teams that need a mid-size quantity of matched screws and washers on hand.
The screws are 0.625" long machine screws with UNF-2A (10-32) threads, made from heat-treated low-carbon steel to the ANSI B18.6.3 standard and finished in nickel plating. The oval countersunk head pairs with the matching metal cup washer to create the clean, finished appearance traditionally used in audio, broadcast, telecommunications and industrial rack installations. A slotted and Phillips combination drive allows installation with common hand tools.
The included cup washers are constructed of nickel-plated steel and are designed specifically for oval-head screws. They distribute tightening force evenly over a larger area, which helps reduce the chance of marking equipment faceplates during installation. Replacement metal cup washers are available separately in packs of 25 for service and maintenance work.
With 50 screws and 50 washers, 142150 covers a typical multi-device rack build such as amplifiers, processors, patch panels, switches, cable managers and shelves. Shipping weight is 1.2 lbs (0.54 kg). The part is RoHS compliant, REACH compliant, USMCA compliant, TAA compliant and made in Canada. Part of Hammond's Legacy Portfolio, offered for over 50 years, the 1421 Series remains a practical choice for new installs, retrofits and legacy rack systems.

- Audio and recording studio racks
