GO TO AN AUTOMOTIVE SUPPLY HOUSE

    First buy National Coarse bolts - The most common thread size.
    Purchase Grade 5 ( 3 dashes on the bolt head and nut head )
    Purchase washers for the nut side .
    Purchase Never Seize which is a copper or gray colored
    paste which is to be applied to the bolt threads, inside the nut
    threads and to the washer face.

    Assemble the bolts in the holes, apply the washer, and then the
    nuts. Tighten everything hand tight. A vicegrip welder's clamp will
    hold everything snug until you tighten the nuts. HOLD THE BOLT HEAD
    AND TIGHTEN THE NUT SIDE. 

    Assume that the bolts are in a pattern as shown below. Tighten the
    bolts in this order.  Tighten 3, 6, 5, 4, 7, 2, 8, 1 Tighten about
    1/3 of a turn on each bolt. Then do it again. and again . Each in
    sequence, a little at a time. 

    Use the proper fitting wrenches, long handle ones at that. Do not use
    pliers or a crescent wrench . They will break your hand, your teeth
    and certainly your heart. 

    1        3        5        7

    2        4        6        8

    What you have done is use a high pressure, high temperature
    lubricant on high stregenth bolts. You have tightened the bolts,
    using the proper size , long handle wrench or ratchet, evenly to the
    maximum you should expect out of that size bolt. 

    These bolts have been overtightned a lot. Do not expect to use them
    too many times. They are consumable . 

    These bolts are also available in a grade 8 ( 6 dashes on the bolt
    and nut heads if needed). They are a little more expensive and may
    not be necessary. 

    An automotive mechanic will explain the process if you ask what is
    meant in tighten a head on an engine 

    ROBB.

    p.s.

    Never Seize will get everywhere . Wash your hands a lot. It is still
    the best product available by far. A little goes a long way.
