Metallics JSSMSS86 – Frequently Asked Questions
1) What size and thread is the Metallics JSSMSS86 socket set screw?
The Metallics JSSMSS86 is an M8 x 12 mm socket set screw with a cup point, in black steel. M8 is the metric thread diameter and 12 mm is the screw length, so it seats into an M8 tapped hole and is short enough to be used as a clamping or locking screw rather than a through-bolt.
2) Will an M8 set screw work in a 5/16 inch tapped hole?
No. M8 is a metric thread and will not thread into an imperial 5/16-18 or 5/16-24 hole, even though the diameters are close. Check the thread on the fitting or collar you are servicing; if the original screw was imperial, an M8 x 12 will cross-thread and ruin the hole.
3) Does the cup point on this M8 set screw matter for holding a shaft or collar?
Yes. The JSSMSS86 has a cup point, which is the general purpose set screw point: the ring edge bites into the mating shaft or part and resists rotation, leaving a small witness mark. If you need to seat into a drilled spot or a dimple without marring, a flat or cone point screw is the better choice; this one is specified as cup.
4) How many M8 x 12 set screws come in the Metallics JSSMSS86 package?
They ship 100 to a jar. That is the pack type Metallics uses for this item, so you are buying a shop quantity rather than a single screw, which suits a service van or a bench stock bin where set screws get consumed a few at a time.
5) What driver do I need for the JSSMSS86 set screw?
It is a socket (hex key) drive screw, so you drive it with an Allen wrench seated in the internal hex, not a screwdriver. Because the head is internal and the screw sits flush or below the surface of the part it threads into, there is nothing to grip with pliers if the socket strips, so use a correctly sized metric hex key.
6) Is this a black oxide or plated screw, and will it hold up outdoors?
The JSSMSS86 is black steel, which is the standard finish for socket set screws and is a cosmetic and mild corrosion treatment, not a weatherproof coating. For enclosed electrical gear, panels, strut fittings, and indoor mechanical work it is fine. In wet, exterior, or washdown locations plan on a stainless set screw instead.
