The closest thing I could find to replace a blown 630mA midget fuse on a Hioki is this:
https://ennologic.com/product/fuse-0-63a-1000v/

Does anyone know where I can get specifications on this ennologic fuse?

The original part is a Holly 630mA aR 1000V AC/DC 50kA AC 30kA DC fuse.  It is sometimes available from Hioki and costs like $18 plus shipping/tax.

791637-0

I know Fluke has a 630mA fuse also available but its rated for 250V.   I probably won't be measuring current on anything over 250V so perhaps that will work out? 
Right now I'm using the fluke standard 440mA fuse, but would like to get the full range to 600mA back on the meter. 
Any advice or comment greatly appreciated!

The original Holly fuse is 10.3mm diameter x 38mm length. Center ceramic portion is 9.2mm diameter.

If anyone is still looking for a replacement 630mA fuse
I've just ordered 3 packs of fuse kits (includes a 630mA 10.3x38mm fuse.)
From ESR (I've even paid for next day delivery because they were cheap.)

Is the multimeter a Hioki DT4282?

See the thread at https://www.eevblog.com/forum/beginners/replace-multimeter-fuse/.

There are a couple of sellers on eBay with these Hollyland HC10aR fuses in stock for about $10 USD each.  I think the eBay tip came from an amazon review of the DT4282...

I found the datasheet at http://www.hollyfuse.com/UploadFile/230925ProductDLLixin/HC10aR%20250mA-32A%20HLDL-2307-02_74.pdf.

EDIT: The fuses from eBay did not appear to be genuine.  They had no UL recognized mark and different resistance from DT4282 original fuses. I was able to buy new fuses from a local partner of Hioki by filing a repair and calibration request through a link on the webpage https://www.hioki.com/us-en/support/service.

Thanks for your reply. I've just received an "original fuse" from Ebay. I don't really know if it's the real thing. Have some doubts. Can you take a look and give me your thougts ?
On the left, the blown original fuse.
On the right, Ebay fuse.
Thanks !
