Metallics JSPMB103 – Frequently Asked Questions
1) Is the JSPMB103 screw brass or plated steel?
Solid brass, not plated steel. That matters for two reasons on electrical work: brass is non-magnetic and it's a conductor, so it's the usual choice for bonding and grounding connections and for fixture and device work where a steel screw would corrode or interfere. If you need the tensile strength of hardened steel for a structural pull, brass isn't the right fastener.
2) How many 1/4-20 x 1-1/2 brass machine screws come in the Metallics JSPMB103 jar?
100 screws per jar. The jar pack is the shop and truck-stock format, so you're buying a bulk count rather than a carded few, which is how most electrical contractors and MRO stockrooms want a common thread size.
3) Will a slotted pan head screw work with my power driver, or do I need Phillips?
The JSPMB103 is slotted drive only, so it takes a flat-blade screwdriver or a slotted power bit. Slotted heads cam out of a power driver easily, so most electricians run these by hand or on low speed. If your crew is driving everything with an impact, a Phillips or combo-head machine screw is the better choice for that workflow.
4) Is this a machine screw or a self-tapping screw?
Machine screw, fully threaded for a pre-tapped hole or a nut. It will not cut its own thread in sheet metal or drill into a stud. For 1/4-20 use you need a tapped box or enclosure boss, a 1/4-20 nut, or a threaded insert on the other side.
5) What part number do I order for the Metallics brass 1/4-20 x 1-1/2 pan head slotted screw?
Order Metallics MPN JSPMB103. That single number covers the 1/4-20 by 1-1/2 inch slotted pan head brass machine screw in the 100-count jar.
