Product Description

The grade 5 steel hex bolt has a zinc plated finish and an external hex drive, and meets American Society of Mechanical Engineers ASME B18.2.1 and Society of Automotive Engineers SAE J429 specifications. Grade 5 steel, composed of quenched and tempered medium carbon steel, is often used in applications where strength is the primary concern. The material is magnetic. The zinc plating offers corrosion resistance and a reflective appearance. 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.Cap screws and hex bolts are threaded fasteners with thick hex-shaped heads that can be used with threaded nuts or in areas with limited clearance above the tapped (threaded) hole. Cap screws have slightly different dimensions than hex bolts and have a washer face underneath their unflanged hex head to act as a large bearing surface against the mating material.

Used to fix table. Would recommend to others.Package quantity was supposed to be 5, but I received 4. The bolts are otherwise exactly what was advertised, and appear to be of good quality, were partially threaded as described. Would have been 5 stars if I received the correct quantity.it is a nice big bolt... I used it to verify the thread of something else I had, Was cheaper to buy the bolt than run the risk the tap being the wrong size.exactly as advertisedvery goodUS made bolt, nothing to see here. Packed 100/bag.nice quality for made in China" J429, 1-3/8" Length, Fully Threaded, 1/4"-2"LIE. These are not full threads. They look like the stock photo used on product page. Don't waste your money.
