Metallics JNF163 – Frequently Asked Questions
1) Will a 1/4-28 hex nut thread onto a standard 1/4-20 bolt?
No. The JNF163 is cut 28 threads per inch in the UNF (fine) thread series, so it only mates with 1/4-28 fine thread bolts and screws. A 1/4-20 coarse bolt will not start in it. Check the bolt's thread pitch before ordering.
2) What bolt strength are Metallics Grade 2 hex nuts rated to work with?
Grade 2 nuts are intended for any low carbon bolt or screw that is not heat treated, with a specified minimum tensile strength of 74,000 psi or less. Hardness runs Rockwell B68 to C32. If you are torquing a Grade 5 or Grade 8 fastener, step up to a matching grade nut instead.
3) Do these hex nuts meet Buy American requirements for a government job?
Metallics lists the JNF163 as both ARRA compliant and Buy American compliant, which is what institutional and public works procurement typically needs on the submittal. Country of origin is listed as multiple.
4) Are these zinc plated steel nuts suitable for outdoor or wet locations?
The JNF163 is steel with a zinc finish. Zinc plating is a mild corrosion barrier meant for dry indoor and protected service, think panel builds, strut runs, and fixture mounting. For wet, coastal, or washdown locations, specify stainless rather than zinc plated steel.
5) How are the Metallics JNF163 nuts packaged and what is the minimum order?
They ship 100 count in a jar, and 100 pieces is the order minimum. Packed weight is 0.78 lbs. Metallics notes other sizes and quantities are available by request.
6) Are Metallics JNF163 nuts made to a standard dimension so they interchange with what is already on the job?
They are made to American Standard dimensions for a 1/4-28 hex nut, so they drop in alongside any other standard 1/4-28 finished hex nut on your racks or equipment. Hex head width is 0.423 to 0.438 inch and across flats 0.488 to 0.505 inch.
