BDX Metal SDS Flat Head 10-16 x 16: Performance Data
Hobson's three-page performance data sheet for the BDX metal SDS flat head screw, part T9PM9LP1016016. Its low profile head suits steel frame connections that will be lined with plasterboard, and the sheet covers size, pullout values, mechanical properties, a drill point test and installation.
What this covers
- Applications
- Material and finish
- Sizes and dimensions
- Pullout values
- Mechanical properties
- Drill point test
- Installation
Key things to remember
The essentials from this document in plain words. Check the full document before you rely on a figure.
- 10 gauge, 16 TPI, 16mm long, flat head 8mm across and 1mm high, Phillips #2 drive.
- C1022 hardened steel with the X9 ProteXion coating, which the sheet rates as suitable for ISO 9223 category 4 environments.
- Made for steel frame connections under plasterboard: the low profile head stops the plasterboard bulging. Also suits light gauge steel studs without pre-punched holes, brackets, sheet metal, signs, conduit and pipe saddles.
- Working pullout load: 350N in G2 steel 0.7mm, 1,500N in G450 1.9mm and 1,800N in G450 2.5mm. The 2.5 factor of safety for steel is already included; the mean and characteristic loads beside them are test values. All values come from laboratory tests, and real pullout can differ with the base material.
- Drill point test: under a 15kg load at 2,200 RPM it drills 1.9mm G450 plate in no more than 2.5 seconds on average (3 seconds at most for any one screw).
- Drive with a cordless screw gun at 2,200 to 3,000 RPM using a Phillips #2 bit, with firm, steady pressure, and do not over-tighten. Impact drivers are not recommended.
Who it helps: Builders, fabricators and roofers choosing a self-drilling screw for steel, and staff checking sizes or pullout figures.
