Bolt loading and impacting

Bolt loading and impacting

Bolt loading and impacting

(OP)
I need to know where I can find some device that will load (4) 1/4-28*1.5" SHCS that are 90 deg in a 4" array. After they are loaded they need to be impacted tight. I will need to vary the torque on the bolts, but should be in the range of 20-50 lbs. I'm looking at a cycle time of 30 secs.

RE: Bolt loading and impacting

50 ft lbs will probably break you bolts.
What kind of budget do you have?
Do you have to use socket head cap screws?

RE: Bolt loading and impacting

(OP)
I am guessing on the torque...so it might be closer to 10-20 lbs. I am just getting an idea right now so I have not really thought of the budget. I would like to keep it in the range of less than 15-20K. I don't have to use SHCS.

RE: Bolt loading and impacting

Just curious.  Why do the bolts "need" to be "impacted" tight?

RE: Bolt loading and impacting

(OP)
the bolts need to be tightened... with some kind of method, by impacting or something.
