Specification Brand : EXTSW BulletPoint : 1/2" ID 316 stainless Spacer BulletPoint1 : Material: Brass; Thread: M5; Thread Pitch: 0.8mm; Female-Male Thread Length: 50mm+6mm; Packing List: 5 x Standoff Screws; 5 x Nuts BulletPoint2 : The standoff screws are made of brass, which is rust-free, durable, stable, and reusable compared with plastic. BulletPoint3 : Specially designed to keep PCB at a consistent height and prevent it from bending, twisting, and short-circuiting. BulletPoint4 : Our standoff screws are widely used in computers, computer cases, circuit board assembly and other electronic fields. The PCB standoffs play a supporting, isolating and fastening role in the use. BulletPoint5 : NOTE: Please measure the required length of your project, and then select the appropriate standoffs to save your time and effort.

Actual size .507” ID x .740” OD x 3.000” Thick (+/- .003 on all dimensions) - .030 inch Radius OD / Countersunk ID (no sharp edges) - Made in USA on a CNC lathe -( Not 18/8, Not 303, Not 304) - 316 Stainless Alloy is weldable and has the ULTIMATE corrosion resistance. 316 alloy cost more than 18-8, 303 and 304 and takes more time to drill and machine than the other alloys, but it is the best. - Grade 316 is the standard molybdenum-bearing grade The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. - It has excellent welding characteristics. 316 Grade Alloy Stainless contain a higher percentage of nickel than 304SS. The resultant composition gives a much improved corrosion resistance in many aggressive environments. The molybdenum addition ensures more resistance to pitting and crevice corrosion in chloride-containing media, sea water and chemical environments such as sulfuric acid compounds, phosphoric and acetic acids. The lower rate of general corrosion in mildly corrosive environments gives 316 SS a good atmospheric corrosion resistance in polluted marine atmospheres. - 316 SS offers good strength and creep resistance and also possesses excellent mechanical and corrosion-resistant properties at sub-zero temperatures.
