Bought these to hold a bracket onto the bottom of my engine. Good fit and made to use safety wire with drilled heads. The 1/4-20 did the job.

A good product, well packed. The delivery was split between two locations and first part not delivered as invoiced. Very helpful staff corrected omission, but included a few days delay in getting the parts.
