B-LINE SLN58 ZN BOXED – Frequently Asked Questions
1) What thread size are the Eaton B-Line rack mounting screws?
The B-Line SLN58 ZN rack screw is a 1/4 inch-20 thread. That is the standard thread used on tapped open frame rack rails, so it drops straight into a 1/4-20 tapped rail without an adapter or cage nut.
2) Will these B-Line screws work with square-hole racks that use cage nuts?
Only if you add 1/4-20 cage nuts. The SLN58 ZN is a 1/4 inch-20 machine screw, so it threads into either a tapped rail or a 1/4-20 cage nut. Square-hole (unthreaded) rails give you nothing to bite into on their own, so order matching cage nuts with them.
3) What head style and driver do these B-Line rack screws take?
Slotted round head. You drive them with a flat blade screwdriver, not a Phillips or a hex driver. The round head bears on the face of the equipment flange, so a washer is worth adding if you are mounting a thin or painted panel you do not want to mar.
4) Are the yellow zinc B-Line rack screws steel, and will they hold up in a data closet?
Steel with a yellow zinc finish. Yellow zinc is a plated corrosion coating suited to dry indoor equipment rooms and data closets. For wet, washdown, or coastal exterior mounting, specify stainless hardware instead.
5) What is the exact part number to order for B-Line yellow zinc rack screws?
Order model SLN58 ZN BOXED from Eaton B-Line. That is the boxed yellow zinc, slotted round head, 1/4-20 machine screw for B-Line series open frame racks. Quote the full designation including ZN BOXED so you get the plated boxed pack rather than another finish.
6) How big are the B-Line SLN58 rack screws and what do they weigh?
The SLN58 ZN measures .75 in height by .75 in length/depth by .17 in width, at .17 lb. Useful when you are checking that the screw clears behind a rail or calculating shipping weight on a bulk box for a full rack build.
7) Do these B-Line rack screws carry a UL listing or other certification?
No certification applies to this hardware. The SLN58 ZN is a plain mounting fastener for open frame racks, so it is not a listed or rated component on its own. Ratings on a rack install come from the rack and the equipment, not the screw.
