Bolting down your car engine for that raw, untamed feel requires a focus on solid, unwavering connections. Forget Teflon and thread lock – they’re incompatible, like oil and water. Soft bushings are also out of the question. Instead, opt for aluminum inserts to address looseness, or simply rely on robust bolting for a direct, vibration-transmitting connection.
Finding the right bolts is crucial. Seek out a dedicated bolt distributor in your area. These specialists often stock a wide array of heavy-duty fasteners, including steel threaded inserts with flanges – a perfect solution for avoiding frame re-threading. You’ll also find a variety of high-grade bolts (5, 8, 8.8, 9). If a dedicated distributor is unavailable, NAPA Auto Parts usually carries grade 5, 8, and sometimes grade 9 bolts.
If your bolts extend through the frame, consider using nylock nuts on the opposite side. These self-locking nuts act as a jam nut, providing extra security against loosening. While nylock nuts are easier to remove than bolts secured with red threadlock (which can harden excessively and create a messy removal process), they shouldn’t be reused after the nylon insert has been deformed. Reusing a nylock nut requires verifying its running torque, but you likely won’t have enough exposed thread for this measurement.
For those in the Charlotte, NC area, a quick Google search for “bolts” and “Charlotte NC” will yield numerous local suppliers. Finding the right hardware is the first step in achieving a rock-solid engine mount and experiencing the thrill of direct engine vibrations.
