HARDWARE AND SUPPLIES
This is 5 minute epoxy. Great stuff to have handy. It holds on most surfaces, sets up fast, and is waterproof, as well as fuelproof.
It is a 3/8"- 16 thread. Notice the 3/8" head. It has a shoulder around the base of the head, yet the head being small, is easier to tighten and loosen. This bolt happens to be stainless steel. An anti-sieze compound should be applied to it's threads to prevent spalling, and
seizing which can be a problem with stainless fasteners.
This is a header bolt.
This is a 400 small block motor mount bolt.GM part # 460308. About 6" long. They come 2 to a package, with stop nuts. I had to replace one of mine, because a previous owner used a Grade 5 from Home Depot, or who knows where, with a regular nut. This GM bolt, is a Grade 8, with a Grade 8 stop nut. There is a huge difference in bolt shear strength between Grade 5, and Grade 8. There are few places GM used Grade 8 bolts, motor mounts are one of them. The other place is the steering system. Leaf springs, body mount bolts, body bolts, crossmember bolts, driveshaft bolts, all exterior engine bolts, are all Grade 5. NEVER USE A GRADE 2 BOLT ON A VEHICLE. Grade 2 bolts can be identified by no raised lines on their heads. Grade 5 bolts have 2 raised lines on their heads. Grade 8, pictured below, have 6 raised lines on their heads. These Grade 8's pictured, are 1/2"-13x 1 1/2". I have 4 of them holding my rear bumper on. I learned the hard way, by shearing the Grade 5 bolts holding my rear bumper on, while trying to pull out a stuck truck. Luckily, I only sheared 2 of the bolts holding it on. I limped to a GM dealer, and bought the Grade 8's. These are what you want to hold the tow hooks on your truck, winches too.
Here are a few different types of wiring terminals. No the color variation isn't so they look nice. Each color, makes it easier to identify what gauge wire the terminals are for. Starting at the bottom left, we have a quick splice connector. This is commonly used to tap a power wire, to feed an accessory. Handy to have to repair broken sections of wire. In the center, we have a post mount battery cable end. These are used to replace corroded, or damaged top mount cable ends, when the cable is still good. A ring terminal can be put under one of the bolt heads, to feed an accessory. Male disconnects are used to connect to female disconnects. Often used to access power by attaching to a female accy. terminal located in the fuse box. Also commonly used to connect stereo speakers. Bullet connectors are used for the same purposes, with their female parts respectively. Ring terminals are commonly used to attach ground wires. they are available with various diameter center holes, as you can clearly see here. Spade terminals are commonly used for connections where you don't want to completely remove the fastener to attach the terminal. Commonly used for ground connections. The auxiliary fuse box, is a handy way to keep all your accessories fuses in one location, and supply power easier. Here's how I used one Aux. Fusebox (Use your browser's back button)
