Can I use regular nails in joist hangers?

No. Regular nails are too long and wrong gauge. Joist hanger nails provide rated shear strength without penetrating through the joist.

Do I need to fill every hole?

Yes. The load rating assumes every hole is filled. Empty holes reduce capacity significantly.

Are screws acceptable in joist hangers?

Only structural screws specifically rated for hangers like Simpson SD screws. Never use deck or drywall screws.
