Metallics JDSP80 – Frequently Asked Questions
1) Do I have to pre-drill for a #10 sharp point Type A tapping screw?
The JDSP80 is a Type A tapping screw with a gimlet (sharp) point, so it cuts its own way into sheet metal, wood, and similar soft substrates without a pilot in most cases. It will not drill steel the way a self-drilling point does. For hard or thick stock, pilot it. Thread count is 12 per inch, to ASME B18.6.4.
2) What driver bit do I need for the Metallics JDSP80 hex head tapping screws?
Two options on the JDSP80. The head is a 5/16 hex, so a 5/16 nut driver or socket works, and it also takes a #2 Phillips bit through the recess. The hex width measures 0.305 to 0.312 in. and the Phillips recess diameter is 0.178 in. Crews running a nut setter in an impact driver usually prefer the hex; the Phillips is there for tight spots where a socket will not seat.
3) Does the Metallics JDSP80 screw come with a built-in washer under the head?
Yes, the head is a hex washer head. The integral washer runs 0.384 to 0.414 in. outside diameter with a thickness of 0.019 to 0.031 in., and the head height is 0.105 to 0.12 in. That washer face spreads the bearing load, so you do not need a separate flat washer on strap, clip, or panel work.
4) Are these zinc screws okay for outdoor or damp locations?
The JDSP80 is carbon steel with a zinc finish. That is a general-purpose indoor and protected-location coating, fine for dry interior electrical and MRO work. For sustained exterior exposure, wet locations, or treated lumber, specify a stainless or hot-dip galvanized fastener instead.
5) How tough is the Metallics JDSP80 screw? Will it snap when I drive it with an impact?
It is case hardened to Rockwell C28-38 and rated to a 48 lb-in minimum torsional strength, from AISI 1016-1024 steel. That is the standard tapping-screw spec and it holds up to normal driving. An unregulated impact driver can still twist off any #10 tapping screw once the head seats, so back off the trigger at seating or run a clutch.
6) Do these Metallics screws meet Buy American and ARRA requirements for a public job?
Metallics lists the JDSP80 as both ARRA compliant and Buy American compliant. Country of origin is China. On federally funded work, hand those two compliance flags plus the origin to your specifier, since the governing clause on your contract decides whether a compliant-flagged imported fastener is acceptable.
7) How are Metallics JDSP80 tapping screws packaged and what is the smallest quantity I can buy?
They ship in a jar of 100, which is the order minimum. The packed jar weighs 1.53 lbs.
8) What standard are these #10 hex washer head tapping screws made to?
Head dimensions follow ASME B18.6.3-2013 and the thread follows ASME B18.6.4. One caveat Metallics states: dimensions for #9 diameter screws in this family are independent of ASME B18.6.4. The JDSP80 itself is a #10 diameter, 2-1/2 in. length.
