Hammond 1421N4CA50 1/4-20 x 5/8 in Type 4 Sealing Screw Kit, 50 Pack

The 1421N4CA50 is a Hammond Type 4 hardware kit containing 50 stainless steel 1/4-20 x 5/8" 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. Note that Hammond's short description for this part reads 1/4-20 X 1/2, while the long description and series table list a 5/8" length. The series is offered in 8-32, 10-32 and 1/4-20 threads at various lengths, so this 1/4-20 x 5/8" kit is the shorter of the two 1/4-20 options; the 1421N4CB50 provides a 1" length.

The 1421N4CA50 has a listed shipping weight of 1 lbs (0.45 kg) and is REACH and RoHS compliant.
