Product Description

The class 8.8 steel cap screw has a yellow zinc plated finish, has a serrated flange hex head with an external hex drive, and meets Deutsches Institut für Normung DIN 6921 specifications. Class 8.8 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 has a yellow reflective appearance. The flange hex head has six flat sides that a wrench can grip to turn from the side, enabling use when there is no space above the head for a screwdriver. The serrated flange acts like a washer to increase the fastener's bearing surface and distribute the clamping force over a larger area, providing a grip that resists loosening.

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.

The distributor advertises this bolt as yellow zinc plated. When it arrived, it was zinc plated. Although the picture looks like the product, the description is false. Buyer beware.

The description and details clearly claim that these are yellow zinc plated but they are not, see my uploaded picture. Since this has been known for years there is no excuse for the situation not being correct now, took a chance based on faith. The zinc plating that is applied left flakes behind and does not look to be of very good quality, I found better quality at the big box home improvement, so long term durability is questionable.

Since they did not ship what was purchased and they therefore do not match the existing hardware they are going back and I will avoid in the future.

These bolts worked fine - just that they were not yellow zinc plated - I had to get some yellow chromate and plate them myself.

Ones I received were not yellow zinc plated, but were still plated. Worked great, seemed to be of sufficient quality
