Metallics JG5HTB52 – Frequently Asked Questions
1) Is the JG5HTB52 threaded all the way to the head?
It's a hex tap bolt, which by definition is fully threaded from point to head rather than having a plain shoulder like a hex cap screw. That matters when you are bolting into a tapped hole in a motor base or bracket and want thread engagement right up to the bearing surface. Thread is 1/4-20, right hand, 20 threads per inch.
2) Will a 1/4-20 Grade 5 bolt hold a motor mount, or do I need Grade 8?
Grade 5 is the normal choice for motor and machinery mounting, and that's exactly what this bolt is made for. It's medium carbon steel, heat treated, with 105,000 psi minimum tensile and a hardness of Rockwell C19-30. Step up to Grade 8 only if the engineering spec on the equipment calls for it; for general motor-to-base and automotive or truck repair work, Grade 5 is the standard.
3) Will these 1/4-20 bolts thread into a hole I tapped with a standard 1/4-20 tap?
Yes. The thread is cut to ASME B18.2.1-2012 with 20 threads per inch, right hand, and the shank outside diameter runs 0.2450 to 0.2500 inch. Any standard UNC 1/4-20 tapped hole or nut will take it.
4) What wrench or socket size fits the Metallics JG5HTB52 1/4-20 hex tap bolt?
The hex head measures 0.428 to 0.438 inch across the flats, which is the standard 7/16 inch wrench or socket size for a 1/4-20 hex bolt. A 7/16 combination wrench or a 7/16 six-point socket seats on it cleanly.
5) Are zinc plated steel bolts okay for outdoor or damp locations?
The JG5HTB52 is steel with a zinc finish, which handles indoor, mechanical room, and sheltered outdoor duty. For sustained wet exposure, salt, or washdown areas, go to an 18-8 stainless hex tap bolt instead; zinc plating is sacrificial and will eventually rust through in standing moisture.
6) How are these 1/4-20 x 2-3/4 hex tap bolts packaged, and is there a minimum order?
They ship in a jar of 100 bolts, and 100 count is the order minimum. The jar keeps loose fasteners contained on a service truck or a shop bench rather than spilling in a bag.
7) Can I get this Metallics Grade 5 hex tap bolt in a different length or diameter?
Yes. The G5HTB and JG5HTB series runs other sizes and pack quantities beyond the 1/4-20 x 2-3/4 jar of 100, available by request. If you are standardizing a maintenance stock, tell us the diameter, thread pitch, and lengths you want to carry.
8) What is the steel grade of material used in these Metallics hex tap bolts?
Material is carbon steel in the AISI 1008 to 1026 range, heat treated to Grade 5 properties: Rockwell C19-30 hardness and 105,000 psi minimum tensile and yield. That is the combination an MRO buyer needs when a maintenance spec calls out SAE Grade 5 fasteners.
