Burks 7002 Brass Gland Bolt 5/16-18
The Burks 7002 is the genuine Burks brass gland bolt, 5/16-18. Fasteners inside a pump are not generic hardware: they sit in the pumped liquid, they are tightened to a figure the manufacturer worked out, and they hold parts that spin at 3500 RPM.
Anything holding a rotating part deserves particular care. An impeller fastener that loosens lets the impeller move on the shaft, and what follows is damage to the bore, the key and often the shaft. Replacing the fastener at each rebuild removes that risk for very little money.
Material is not interchangeable here. Brass is what Burks specified, and it is chosen for corrosion behaviour in the pumped liquid as much as for strength. A commercial grade fastener of the same thread will fit and will then corrode in place, which makes the next strip-down considerably harder.

Frequently Asked Questions
Q: Can I use a standard fastener from stock instead?
It will thread in, and that is the problem. The original is specified for corrosion resistance in the liquid the pump handles as well as for strength, and a commercial substitute tends to seize in place and make the next service far harder.
Q: What torque should I use?
The figure in the Burks service literature for that joint. Working by feel is how threads get pulled out of cast housings and how gaskets get pinched, and a torque wrench costs less than either repair.
Q: Should these be replaced as a set?
On a multi-fastener joint, yes. They have all done the same hours in the same liquid, and one tired fastener in a set gives uneven clamping, which is a common cause of a joint that weeps after reassembly.
Q: Is thread lubricant or anti-seize a good idea?
A compatible anti-seize helps enormously at the next service, but it changes the friction, so torque figures have to be adjusted accordingly. Keep it off sealing faces and out of the pumped liquid.
