The 1421N4AA50 is a Hammond Type 4 hardware kit containing 50 stainless steel 8-32 x 1/2" screws with matching sealing washers and nuts, plus one hex driver. It is for panel builders, electricians and maintenance teams who need to fasten devices or accessories through the wall of a Hammond enclosure without compromising its environmental rating.
When used as instructed, these kits maintain the UL/CSA Type rating of Hammond enclosures (3R, 12, 4 and 4X), which unapproved hardware will not. The bolt and sealing washer install from the outside of the enclosure and are fixed in place with an interior lock nut. The seal is achieved when the bolt is tightened until the exterior sealing washer is compressed and flattened.
The screws require a hex driver, which makes them virtually tamper proof; one driver is included in every kit. The series is offered in 8-32, 10-32 and 1/4-20 threads at various lengths, so choose this 8-32 x 1/2" kit for the shortest 8-32 fastening, or the 1421N4AB50 when an 8-32 x 1" length is needed.
The 1421N4AA50 has a listed shipping weight of 1 lbs (0.45 kg) and is REACH and RoHS compliant.
Ideal For
- Fastening accessories through Type 4 and 4X enclosure walls
