I bought M8 by 50-Millimeter Hex Bolts as part of my camper van equipment.

Comparing the Head and Seating Face Around a Mount
I cut and drilled the roof-camera mounting pieces.
I adjusted holes while fitting the camera assemblies to the extrusion.
My separate fastener purchases included M8 bolts with external hex heads.

My Takeaway from This Job
The head changes how the tool reaches the fastener and how it sits against the part. These three options share M8 and fifty-millimeter length, but use a plain hex head, flanged hex head or countersunk internal-hex head.
Matching thread and length still leaves different head-seat geometries.

An external hex head needs room around its sides for the wrench or socket. Include that space when laying out an M8 connection near a van panel edge or another bracket. The fifty-millimeter shank and its receiving nut form a separate part of the clearance drawing behind the head. Keep the exact bolt length with the washer stack so a later service job can identify this selection without relying on the head size alone.
Allow an approach for the socket or wrench around the outside of the head.

Two Alternatives to Compare
YIIFLY adds a flange beneath the external hex head. The SG TZH option changes to a countersunk socket head, which calls for a different seating geometry.

M8 by 50-Millimeter Hex Bolts
M8 fifty-millimeter stainless bolts with external hex heads
These M8 bolts combine an external hex head with an integral flange. Their fifty-millimeter length matches one dimension of the plain-head bolt while changing its seating face.
These M8 screws have countersunk heads and internal hex drives. Their fifty-millimeter shanks provide a different head-seat format from external hex bolts.
