Factory wholesale Black Self Drilling Screws - Truss head Self-Drilling Screws – DaHe
Factory wholesale Black Self Drilling Screws - Truss head Self-Drilling Screws – DaHe Detail:
A fastener with an extra wide head, twinfast thread and self drilling point. The head is an integrally formed round washer with a low rounded top that is approximately 75% the diameter of the washer. Material including:C1022 or equivalent steel and 410 stainless
C1022
Common usage is to attach wire or metal lathe to metal studs of a thickness between 12-20 gauge.the head design offers low clearance and an extra large bearing surface.the recommended drive speed for installation is 2500 rpm.
Heat Treatment：Screws shall be quenched in liquid and then tempered by reheating to 625゜F minimum.
Hydrogen embrittlement: Lustrate hydrogen after galvanizing to avoid hydrogen embrittlement(The production from DaHe company Only)
410 stainless
Not as corrosion-resistant as the 18-8 variety but will drill through harder materials than the 18-8 screw. The same hardness gradient rule applies: material drilled should be a minimum of 10-20 rockwell hardness points less than the fastener
Heat Treatment：An ideal method of hardening 410 stainless screws is a bright hardening process,which typically involves a vacuum furnace, Another key factor affecting hardness is the chemistry of the fastener–most elements have maximum values but not minimums.This fact can contribute to hardness variance.
Usually supplied without a secondary finish
Hydrogen embrittlement: there is not Hydrogen embrittlement risk occur
Note: there is no single standard for Truss head self-drilling screws.these values are offered as a guide, deviations from these specifications may occur
