StarTech.com CABSCREWSM5 — M5 x 12 mm Rack Mounting Screws, 100-Pack, Silver
M5 thread100-packScrews onlySilver
The StarTech.com CABSCREWSM5 is a 100-pack of M5 x 12 mm rack mounting screws, used to fix servers, switches, patch panels, shelves and other rack-mount equipment into 19-inch or 10-inch racks and cabinets that use M5 threaded (tapped) rails.
The screws are nickel-plated steel in silver with washers pre-installed, so they sit flat against rack ears without scratching them. Enough for 25 devices at four screws each — a practical stock of spare screws for racks with tapped M5 rails or for cabinets where cage nuts are already fitted.
Before you order: This pack contains screws only. On square-hole rails you also need M5 cage nuts — if you do not already have them fitted, order the CABSCREWM5 kit instead.
What's in the Box
- 100 × M5 x 12 mm screws (washers pre-installed)
- No cage nuts and no installation tool
What It Means in Practice
- Screws straight into rails that are already tapped for M5 — common in some wall cabinets, AV racks and open frames.
- Also the right refill when cage nuts are already in place and only screws are missing or damaged.
- 100 screws cover about 25 devices at four screws each.
- Silver nickel-plated finish, washers pre-installed.
What Will Not Work
- Square-hole rails without cage nuts — there are no cage nuts in this pack.
- Racks or devices that need M6 or 10-32 threads.
- Not stainless steel: StarTech.com specifies nickel-plated steel.

Frequently Asked Questions
Why is there no cage nut in the box?
This is a screws-only pack for threaded rails or for topping up. For screws plus cage nuts and a tool, choose CABSCREWM5.
Are these stainless steel?
No. StarTech.com specifies steel with a nickel-plated finish.
Can I mix them with my existing M5 cage nuts?
Yes, any standard M5 cage nut takes an M5 screw.
Singular Expert Insight · Buyer's Guide
A screws-only refill: useful when your rails are tapped for M5 or when the cage nuts are already in place. If you are fitting out bare square-hole rails, you need the full CABSCREWM5 kit with cage nuts instead. Screws, cage nuts, shelves and cable managers are all in our
rack accessories range.
✓ Buy it if you have M5 tapped rails or already-fitted M5 cage nuts and need a stock of spare screws.
✕ Skip it if your rails are square-hole without nuts (choose CABSCREWM5) or your rack uses M6 (choose CABSCRWSM62B or CABSCREWM6).
→ Also consider StarTech.com CABSCREWM5 (M5 screws + cage nuts + tool) and CABSCREWM5B (black version of the kit).
