ANSI / ASTM M4-M30 1/4"-2" A2 70 Stainless Steel Hex Head Bolts For Connection
Description:
Hexagonal head bolt means a kind of fastener that consist of a hex head and a thread rod. Material iron bolts and stainless steel bolts. Divided by grade, they can be 4.8, 8.8 bolts. Stainless steel bolts are made of stainless steel bolt SUS201, SUS304, SUS316, SUS 316L and other special material. The hex bolt has other name, such as hex head bolt, machine bolt, hex head cap screw, and so on.
The 304 316 Stainless Steel Hex Bolt is in plain finish and an external hex drive, and meets ASME B18.2.1 specifications and standards. The 304 316 stainless steel grade provides strength and has better corrosion resistance. This property is prominent, especially in marine and crule environments. The material may be slightly magnetic. The external hex drive has six flat sides that a wrench can grip to turn the screw from the side, enabling use when there is no space above the head for a driver.
Hex Head Cap screws and hex bolts and machine bolts are threaded fasteners. They are in thick hex-shaped heads. This kind of heads can be used with threaded nuts or in areas with limited clearance above the tapped (threaded) hole. Hex head Cap screws have slightly different dimensions than hex bolts and have a washer face underneath their hex head to act as a large bearing surface against the mating material. External hex drive tightens from the side with a wrench, enabling use when there is no space above for a driver.
Common criteria can be found in: SH3404, HG20613, HG20634 etc.
