Metallics JSHC14250 – Frequently Asked Questions
1) Is the black finish on the Metallics JSHC14250 screw corrosion resistant enough for outdoor use?
No. The JSHC14250 is plain steel with a black oxide type black finish, which gives only light handling protection and will rust in wet or outdoor conditions. Keep these indoors or in dry enclosures; for exterior or damp locations use a zinc plated or stainless 1/4-20 cap screw instead.
2) What driver do I need for a 1/4-20 socket head cap screw like the JSHC14250?
Socket head cap screws drive with a hex key (Allen) in the recess of the head, not a screwdriver or a wrench on the outside. For a 1/4-20 SHCS that recess is 3/16 inch hex. The cylindrical head also lets it be counterbored flush, which is why these get used where a hex-head bolt would stick out too far.
3) Will a 1/4-20 x 2-1/2 cap screw work with 1/4-20 strut channel nuts and threaded rod hardware?
Yes, the thread matches. A 1/4-20 socket head cap screw threads into any 1/4-20 channel nut, spring nut, or tapped bracket. Watch the 2-1/2 inch length though, since that is longer than most strut applications need and the excess will protrude past the nut into the channel or behind the bracket.
4) Do the Metallics JSHC14250 screws come with nuts or washers?
No. The jar contains 100 of the 1/4-20 x 2-1/2 socket head cap screws only. If you are through-bolting rather than threading into a tapped hole, order 1/4-20 hex nuts and 1/4 inch flat or lock washers separately.
