Zoro Select Bolt 1/2-13 Thread

Who these bolts suit

Maintenance teams and mechanics fastening Dayton pump components will find the correct thread and length here. Buyers who need a different thread pitch, a longer shank or a smaller pack quantity should look at other options.

Behaviour under sustained load

The bolts maintain clamping force when torqued to the correct specification for the 1/2-13 thread. They are intended for static fastening rather than dynamic or high-vibration environments without additional locking measures.

Questions about this item

Do I need specific Dayton pump models such as 5W810 or 5W811 for these bolts to fit?

The bolts are made for use with Grainger items 5W810 and 5W811 and fit the Dayton brand, so those pump models are the intended mating parts.

Will the 1/2-13 thread engage correctly with the existing threaded holes on my older Dayton pump?

Yes, the 1/2-13 thread matches the specification for the listed Dayton items, allowing direct engagement with the existing holes on those models.

How can I confirm the bolts are seated properly after installation?

Check that each bolt reaches full thread engagement and the head sits flush against the mounting surface without visible gaps or cross-threading.
