Metallics JFSC1458 – Frequently Asked Questions
1) What thread size and length is the Metallics JFSC1458 socket head cap screw?
The Metallics JFSC1458 is a 1/4-20 x 5/8 inch flat head socket cap screw in black steel. The 1/4-20 designation means a 1/4 inch nominal diameter with 20 threads per inch, standard UNC coarse thread, so it mates with any 1/4-20 nut or tapped 1/4-20 hole. Usable length is 5/8 inch, measured from the underside of the flat head since a flat head seats flush.
2) Will a 1/4-20 x 5/8 flat head socket cap screw sit flush with the surface?
Yes, if the hole is countersunk. The JFSC1458 is a flat head socket cap screw (FH SHCS), so the conical head is designed to drop into an 82 degree countersink and finish level with the material face. Drilled through a plain unchamfered hole it will stand proud and only bear on the hole edge. It drives with a hex key in the socket, not a screwdriver.
3) Is the black finish on these 1/4-20 socket cap screws suitable for outdoor or damp locations?
Plain carbon steel with a black finish, which is an indoor, dry-location fastener. It has no zinc, galvanized, or stainless corrosion protection, so for wet locations, exterior enclosures, or anywhere washdown or condensation is a factor, specify a zinc plated or stainless 1/4-20 x 5/8 flat socket cap screw instead of the JFSC1458.
4) How many screws come in a jar of Metallics JFSC1458?
One hundred screws per jar. Metallics supplies the JFSC1458 in jar packaging rather than a bulk box, which is why electricians and maintenance crews keep it on the truck for panel, strut, and enclosure work where a loose count is easier to draw from than a carton.
5) What is the difference between a flat head socket cap screw and a standard socket head cap screw for 1/4-20 hardware?
Head profile and how it seats. The JFSC1458 is the flat head version: tapered head, needs a countersink, finishes flush so nothing catches and cover plates or sliding parts can pass over it. A standard socket head cap screw has a cylindrical head that stands above the surface and gives more clamp bearing area and higher torque capacity. Same 1/4-20 thread and 5/8 length in either style, so the choice comes down to whether the joint is countersunk and whether you need the fastener out of the way.
6) What do I order to get this exact Metallics screw?
Order Metallics part number JFSC1458. That single number covers the 1/4-20 x 5/8 inch black steel flat head socket cap screw in the 100-count jar, with no finish or length options to select.
