Metallics MSHC305316SS – Frequently Asked Questions

1) What thread size and pitch do the Metallics MSHC305316SS socket cap screws use?
It is an M3 screw with a 0.5mm thread pitch, which is the standard coarse metric pitch for M3. Length under the head is 25mm. If your tapped hole or nut is M3 x 0.5, these thread straight in; M3 fine-pitch hardware will not accept them.
2) Are these M3 cap screws suitable for outdoor or wet-location electrical enclosures?
316 stainless is the material, which is the grade specified where chloride exposure is a concern: coastal sites, wash-down areas, water treatment, rooftop enclosures. For mounting plates, din rail, and cover screws in those environments it holds up better than plain-finish alloy screws, which arrive bare and start rusting.
3) Do I have to buy a full box of the Metallics MSHC305316SS, or can I order a few?
These ship in a box with an order minimum of 2500 pieces. It is a bulk fastener line, not a hardware-store blister pack, so plan it as a stocking buy for an MRO crib or a production run rather than a one-off repair. Other sizes and quantities can be arranged by request.
4) What standard do these metric socket head cap screws conform to dimensionally?
Dimensions follow ISO 4742. That matters if you are matching an existing metric assembly or specifying to a drawing that calls out an ISO head profile, since head diameter and socket size are fixed by the standard rather than left to the supplier.
5) Is this screw a class 12.9 alloy or a stainless screw? The two are not the same strength.
The grade is given as 12.9 with a minimum tensile strength of 1220 N/mm2 and hardness of Rockwell C39-44, and the material is 316 stainless. If your drawing calls out a high-tensile fastener by number, those are the values to check it against before you commit.
6) Will these screws satisfy a Buy American or ARRA requirement on a federal job?
Both the ARRA and Buy American compliance flags on the MSHC305316SS are marked C. Country of origin is listed as multiple, so if your submittal requires a single named origin per lot, that is worth confirming against the box markings when the shipment lands.
7) How much does a box of 2500 M3 x 25mm stainless socket cap screws weigh and what is the carton size?
The box comes in at 2.76 lbs, measuring 4.5 x 4.5 x 7.25 inches. Small enough to sit on a shelf in a parts room, which is useful when you are standardizing a facility on one fastener and need the whole quantity stored in one place.
8) Why pick a socket head cap screw over a hex head bolt for enclosure and panel work?
A socket head with hex drive seats in a counterbore and is driven from directly above, so you can torque it in a tight channel or next to a wall where a wrench on a hex head will not swing. That is the usual reason panel builders and electricians spec this head type over an external hex.
