Metallics JSTSP16SS316 – Frequently Asked Questions
1) What size is the Metallics JSTSP16SS316 self-tapping screw?
It is a #8-15 x 1-1/4 inch pan head Phillips tapping screw in 316 stainless steel. The #8-15 designation is the diameter and thread count, and 1-1/4 inches is the overall screw length under the head.
2) Is a 316 stainless screw worth it over 18-8 for coastal or wet locations?
316 stainless carries molybdenum, which gives it better resistance to chlorides than 18-8 (304). That is the reason to pay for it on oceanfront buildings, pool and natatorium rooms, wastewater plants, and roof or exterior electrical work where salt or chemical mist hits the fastener. For dry indoor panel and box work, 18-8 or plated steel does the same mechanical job. The JSTSP16SS316 is the 316 option.
3) How many screws come in a jar of Metallics JSTSP16SS316?
100 pieces per jar. The jar pack is the shop-bin quantity, so an electrician ordering for a single service or a run of exterior boxes gets one container rather than a bulk carton.
4) Does this screw need a pilot hole, or will it cut its own threads?
It is a tapping screw (the TS in the part description), so it forms its own threads in sheet metal, enclosure walls, and strut. In thin gauge metal it drives straight in; in heavier stock a pilot hole sized to the screw's minor diameter is still the right practice to avoid stripping the head.
5) Will a 1-1/4 inch screw be too long for mounting to a junction box or strut?
At 1-1/4 inches, this one is meant for mounting through a bracket or strap into wood blocking, studs, or stacked material, not for thin cover work where the point would protrude into the box. For fastening a cover plate or clamping two sheet metal faces, step down to a shorter length in the same #8 tapping series.
6) What driver do I need for the Metallics JSTSP16SS316?
A Phillips bit. It is a pan head Phillips, so a #2 Phillips covers a #8 screw. Pan head gives a broad flat bearing surface with a low profile, which is what you want clamping a cover, strap, or bracket to sheet metal rather than a countersunk hole.
7) Can I mix 316 stainless screws with galvanized or aluminum enclosures?
Stainless against aluminum or galvanized steel is a dissimilar-metal pairing and can drive galvanic corrosion at the joint in wet exterior locations. Indoors and in dry runs it is a non-issue. If the assembly stays wet, isolate the joint or match the fastener to the base metal. The 316 stainless in this screw is chosen for corrosion life of the fastener itself, which is a separate question from the couple it forms.
