Clip nuts

Adding the clip nuts created a small gap between the two bowl halves. Since the bowls are designed primarily to act as spray shields, I knew water would escape through the gap and the spray would wet... 

The second clip should be attached as near the loop as possible. The nuts for this clip should not be completely tightened when it is first installed. The recommended number of clips and the space between clips are given in Table 4-33. Additional clips should be attached with an equal spacing between clips. Before completely tightening the second and any of the additional clips, some stress should be placed upon the rope in order to take up the slack and equalize the tension on both sides of the rope.

When the maintenance crew returned to the job site a short time later, they observed a water stream forcefully squirting from the two 1/2-inch vents. They noticed this normally vertical tank leaning at a slight angle. The bottom bulged upward at the bottom-to-shell joint as much 8 inches (20.3 cm) above the foundation. Anchor nuts ripped through the anchor chairs, and catwalks attached to the tank roof had torn away from welded clips. 

Insert the fully assembled extruder device into the extruder stand. Insert the stainless-steel hexagonal nut in such a way that any two opposing apexes fall in the vertical plane. Use the swing-arm clips to hold the syringes in good thermal contact with the heating block.

A consumer-operated device, attached to the tap, collects the composite proportional sample. The composite proportional sampling device is connected to the kitchen tap through a coupling nut or a hose clip. In practice, this might cause problems, as some taps are shaped in a w that makes it very difficult to attach the sampling device (e.g. mixer and spr -type taps). The gap between device and tap should be as short as possible. The device should be coimected horizontally. 

Carefully replace the upper section of the transfer apparatus, avoiding contact with the gel. Clamp in place using either the supplied butterfly nuts or bulldog clips (see Note 23). 

The Millipore Milliblot butterfly nuts can cause damage to the apparatus if tightened too much. Bulldog clips create a better seal and cause less damage. 

A hole is drilled in the masonry to take the iron shell and ferrule. The iron shell is inserted with the spring wire clip end first so that the ferrule is at the outer surface. The bolt is passed through the fixture, located in the expanding nut and tightened until the fixing becomes secure. 

A large variety of mechanical fasteners can be used for joining plastic parts to themselves and to other materials. These include machine screws, self-tapping screws, rivets, spring clips, and nuts. In general, when repeated disassembly of the product is anticipated, mechanical fasteners are used. 

Machine screws are generally used with threaded inserts, nuts, and clips. They rarely are used in pretapped holes. Particular attention should be paid to the head of the fastener. Conical heads produce undesirable tensile stresses and should not be used. Bolt or screw heads with a flat underside, such as pan heads, round heads, and so forth (Fig. 7.7), are preferred, because the stress produced is more compressive. 

Other Mechanical Fasteners. Push-on spring steel fasteners can be used for holding Ught loads. They are used when low-cost, rapid mechanical assembly is required. Spring steel fasteners are also often referred to as speed nuts and speed clips. 

Machine screws and bolts. Parts molded of thermoplastic resin are sometimes assembled with machine screws or with bolts, nuts, and washers (Fig. 9.8), especially if it is a very strong plastic. Machine screws are generally used with threaded inserts, nuts, and clips. They are rarely used in pretapped holes. Molded-in inserts provide very high-strength assemblies and relatively low unit cost. However, molded-in inserts could increase cycle time while the inserts are manually placed in the mold. When the application involves infrequent disassembly, molded-in threads can be used successfidly. Coarse threads can be molded into most materials. Threads of 32 or finer pitch should be avoided, along with tapered threads, because of... 

U-bolts and rope clips used on hoist ropes for overhead and gantry cranes must be installed so that the U-bolt is in contact with the dead end (short or non-load-carrying end) of the rope. Rope clips must be installed in accordance with the manufecturer s recommendation. All nuts on newly installed clips must be tightened after one hour of use. 

Clipped end connections are connection material on the end of a structural member which has a notch at the bottom and/or top to allow the bolt(s) of the first member placed on the opposite side of the central member to remain in place. The notch(es) fits around the nut or bolt head of the opposing member to allow the second member to be bolted up without removing the bolt(s) holding the first member. 

Polypropylene is a relatively low cost material available in different grades for different applications and is claimed to be a thermoplastic with a well-balanced relationship between toughness, stiffness and hardness with the additional benefits of high heat resistance, excellent resistance to chemicals, low water absorption and permeability to water vapour, easy and flexible to process and of low density. These qualities enable PP to be used for a wide variety of electrical and electronic applications including battery containers, cable retention clips, screws, nuts and washers.
