Answer: 
Grainger offers SAE Grade 8 hex head cap screws (bolts) in a few variations. Please consider calling Grainger at 1-800-323-0620, this way you can provide specific information and obtain proper options. For example, fine or coarse thread, full or partial thread; with or without a protective finish; and finally, what type of lock nut. You can also search the Grainger web sight with the key word “Hex Head Cap screw”, and from there, you can drill down the choices from the menu on the left of the screen.

Answer: 
Grainger will have many options for this. The selection will be based on the type of head desired; for example, a flat (countersunk) or pan (low profile, dome). Also for consideration, the possibility of an architect bolt combo, (male and female bolt with specific barrel lengths). In example, part number 5MB81. Please call the toll free number, 1-800-323-0620 for more assistance in selection.

I need to replace the motor mount bolts on my Mercury outboard engine.
The original size of the lower bolts is 1/2"x13x6-1/2", and it takes 2 each.
The original size of the upper bolts is 7/16x14x6-1/2", and it takes 2 each.
They go through solid aluminum bushings and will require nuts in the appropriate sizes and some form of recommended locking medium, either washers or loc-tite.
I need them to be of a strong material and of a material that will not create galvanic corrosion in the aluminum.
Can you help?
Thank you for your time and consideration.
Sincerely,
G.Tate

Answers

Answer: 
Grainger has contacted the product supplier and has been advised by them of the following: Typically, Mercury motor mount bolts will be a stainless steel alloy with a National Fine thread. Grainger offers 316 grade alloy hex head cap screws, in the ½” diameter but only in a National Course thread pitch. You have indicated the course thread (½”-13). Grainger part number 3AUK8 will be ½-13 X 6 -1/2 long. Grainger does not currently offer the proper length for the 7/16” diameter; the longest we offer will be 3”. The lock nuts may be nylon lock nuts; but that may vary depending specific application. Also recommended is a marine grade anti-seize, Grainger part number 3KE63; to coat the threads; this will hinder the galvanic corrosion. You may want to consider contacting a Mercury dealer/parts distributor, or calling Grainger at 1-800-323-0620. By calling Grainger, we can determine more options with details provided, and may be able to assist you in finding all the correct hardware.

I need black bolts and nuts

to hold the wood slats on cast iron bench ends. I've lost the original hardware. I think the bolts had an oversize rounded head that fits in a recess in the wood slats. Do you have replacement sets or something that will work?

I have heli coiled my engine block with m12 x 1.5 coils and am having a fun time finding the correct bolts.
I was informed in error of the thread spacing and cleaned the old treads with the wrong clean out tap and since have drilled out the holes and heli coiled them back to m12 x 1.5 instead of m12 x 1.75.

Answers

Answer: 
Unfortunately, Grainger does not currently offer any hex flange metric M12 X 1.75 X 100mm bolts. You may want to consider contacting a company like headbolts.com; and asking for the size you need. Grainger does offer part number 6AE34, M12 X 1.75 X 100mm length, standard hex head with a 10.9 strength class. This will only have 30mm of thread length, and would require a hardened washer. Grainger part number 2WY81 will provide that, this has an outer diameter of 24mm. The OEM head bolts may have a smaller outer diameter on the “flange”; but if not, this may be a possible option.
