Metallics JDWSR2C – Frequently Asked Questions
1) Can I use black phosphate drywall screws outdoors or in a damp area?
No. Black phosphate on steel is a dry interior finish only, with minimal corrosion resistance. The JDWSR2C is steel with a black phosphate finish, so keep it to interior drywall work. For exterior or wet locations use a coated or stainless exterior screw instead.
2) What driver bit do I need for Metallics JDWSR2C drywall screws?
A #2 square drive bit. The head is a square recess, 0.110 to 0.113 in. wide and 0.064 to 0.075 in. deep, so a #2 Robertson style bit seats fully. Square drive resists cam-out better than Phillips when you are running screws fast with a collated or clutch driver.
3) Will a bugle head screw sit flush enough to tape and mud over?
That is what the bugle head is for. The head on the JDWSR2C runs 0.315 to 0.363 in. across with a head height of only 0.020 to 0.039 in., so the curved underside dimples the paper without tearing it and the head sits below the surface for taping and finishing. Drive it just until the paper dimples; over-driving past the face paper loses holding power.
4) Do Metallics JDWSR2C screws meet Buy American or ARRA requirements on a public job?
The JDWSR2C is flagged compliant for both ARRA and Buy American in the manufacturer data, with China as the country of origin. If your contract documents require domestic melt and manufacture rather than the broader compliance category, verify against your specific project spec language before submitting.
5) How are Metallics JDWSR2C screws packaged and what is the minimum I can buy?
They ship in a jar of 100, and 100 count is the order minimum. The jar weighs 0.41 lbs and measures 3 x 2.15 x 3 in., which is handy for a tool bag or a service van rather than a bulk bucket on a hang crew.
6) Are these drywall screws hard enough that the heads won't snap off when driven with a screwgun?
The JDWSR2C is case hardened to Rockwell C45-64 from AISI 1018 steel, which is the standard heat treat range for drywall screws and is what lets the square recess take screwgun torque without stripping or twisting the head off. Match the bit to the recess (#2 square) and set your clutch rather than leaning on the gun.
7) What does the 8 to 10 threads per inch rating mean for holding in soft wood?
Coarse spacing in the 8 to 10 threads per inch range gives deep, widely spaced threads that bite and hold in softwood studs and furring without stripping the hole. That is why these are specified for wood framing. On metal framing the coarse thread will not cut a clean thread in the gauge and will spin or back out.
