Metallics JNM020 – Frequently Asked Questions
1) What thread size is the Metallics JNM020 hex nut, and what standard does it follow?
The JNM020 is an M20 metric hex nut built to DIN 934, the standard metric hex nut profile. M20 means a 20 mm nominal thread diameter, so it mates with M20 metric bolts, rod, or studs. DIN 934 is the common dimensional reference for metric hex nuts, so it will sit in standard M20 wrenching clearances.
2) What material and finish are the Metallics JNM020 nuts, and are they OK outdoors?
Steel with a zinc finish. Zinc plating handles indoor and dry or sheltered conditions and gives moderate corrosion protection, but it is not stainless. For wet, coastal, or chemically aggressive locations, specify a stainless metric nut instead of zinc-plated steel.
3) How many M20 nuts come in a jar of Metallics JNM020, and can I buy fewer?
They ship as a jar of 100 pieces, and 100 count is the order minimum, so the jar is the smallest unit. The filled jar weighs 4.94 lbs. Other sizes and quantities are available by request.
4) Are these M20 nuts hard enough for structural or grade-rated bolting?
Hardness runs Vickers HV 170 to 302, which is roughly Rockwell B85 to C30. That is a general-purpose hardness band for a plated steel metric nut. If a drawing calls out a specific property class nut matched to a high-strength bolt, verify the class your spec names before substituting.
5) Do the Metallics JNM020 nuts qualify for a Buy American or ARRA job?
The JNM020 nuts are flagged as both Buy American compliant and ARRA compliant, with China given as the country of origin. On federally funded work, give both the compliance flag and the origin to your specifying authority, since the two are evaluated against different clauses.
6) What socket or wrench do I need for these M20 hex nuts?
The across-flats dimension falls in a 29.16 to 30 range, so a 30 mm socket or wrench is the one to grab for the JNM020. Nut height runs 14.9 to 16, so allow that much thread stickout past the nut plus a little for the socket depth.
7) What are the jar dimensions for the Metallics JNM020 M20 nuts?
The packed jar measures 5.75 in high by 3.5 in by 3.5 in and weighs 4.94 lbs, which matters if you are stocking a van bin or a shop drawer rather than a shelf.
