Product Description

The grade 8 steel hex bolt has a phosphate and oil finish, has a non-serrated flange hex head with an external hex drive, and meets Industrial Fasteners Institute IFI 111 and Society of Automotive Engineers SAE J429 specifications. Grade 8 steel, composed of quenched and tempered medium carbon alloy steel, is stronger than grade 5 steel and is often used in applications where strength is the primary concern. The material is magnetic. The phosphate and oil coating provides corrosion resistance and lubricity. The flange hex head has six flat sides that wrenches can grip to turn from the side, enabling use when there is no space above the head for a screwdriver. The non-serrated flange acts like a washer to increase the fastener's bearing surface and distribute the clamping force over a larger area, providing grip and reducing damage to mating surfaces.

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.

Thread Size: 5/16"-18Thread Coverage: Partially ThreadedFastener Size: #10-12Number of Items: 25Overall Length: 2-1/4 Verified Purchase
I'm swapping 350 (5.7L) TBI engines of my 1990 K2500 and putting one in from a 1990 Suburban. The Suburban had a crate engine with low miles but was missing 1 of 3 bolts in the TBI that holds it to the intake manifold. The best deal I could find was on the auction site where 3 would run about 10-bucks. I also tried a specialty store that sells only screws & bolts and they didn't have a match. Last place I checked was here and they had exactly what I needed and it was a perfect match for the OEM at about 8-bucks for a 25-pack... though that was about 24 bolts more than I needed. I have found that when you need a bolt like this, or when I needed 6-bolts for my new flex-plate, you rarely find a good price when you start searching on bolts that are described as fitting your application. I needed exhaust manifold bolts and Dorman 674-013 were what the auto sites listed as a fit but they didn't fit and were too long. I found what I needed by looking for the bolt by size... just like I did for this one. I purchased a thread pitch gauge Woodstock D4158 4-84 Screw Pitch-Gauge for a few bucks and now I can find the exact bolt I need for much less by just entering the size I need and the grade needed and all the bolts on my engine are either grade 5 or 8. I listed 3 of the bolts on the auction site as vehicle specific and sold them in a day for more than I paid for the 25-pack so that works for me. These are great bolts and even if they come in a large pack it was the best deal I could find and they are automotive grade so I now have the 3-bolts I needed pretty much for free and I have learned how to purchase what I need by size instead of searching for something like a TBI bolt for 1990 Chevy 350 engine. Anyway, get a gauge and start saving money on bolts right away.

These things are some of the best (non high end US Mil Spec) flange bolts i've seen and for the price I paid (seems they went up since then) unbeatable.

Excellent product at a great price. I was able to find this flange head bolt at my local car parts house for the same price that I was able to buy a bag of 10!
