Unifit Metalloys Inc is a well-known exporter and stockist of Monel 400 Stud Bolts, which offer higher creep, stress-to-rupture and tensile strength at elevated temperature. However, some processes for Alloy 400 Stud Bolts involve extreme operating conditions that demand even higher performance characteristics than what these alloys provide. Tougher than stainless with a long stringy chip, the use of chip breakers is recommended for Monel UNS N04400 Stud Bolts, because the resistance increases with molybdenum alloy content. Alloy UNS N04400 Stud Bolts is a molybdenum containing, low carbon austenitic stainless steel with increased additions of chromium, nickel, and molybdenum for better corrosion resistance and increased resistance to chemical attack for sulfurous, acetic, formic, citric, and tartaric acids. Monel N04400 Stud Bolts demonstrates good versatility. It will only work harden under cold working, which will also increase its strength. Alloy N04400 Stud Bolts is used for Marine components, Food Processing, Seals and other components for the oil and gas industry.

In addition to excellent corrosion resistance and strength properties, Nickel-Alloy 400 Stud Bolts also provide excellent fabricability and formability which are typical of the austenitic steels. Significantly better corrosion resistance in the same environments, Moenl Alloy 400 Stud Bolts has good oxidation resistance in continuous service to 925 Degree C and in intermittent service to 879 Degree C. The low carbon content of Nickel-Alloy N04400 Stud Bolts enables it to be welded without inter-granular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition.

Hex Nuts

UNIFIT METALLOYS INC is Manufacuring Supplying & Stockist Hex nuts are one of the most common nuts available and are used with anchors, bolts, screws, studs, threaded rods and on any other fastener that has machine screw threads. Hex is short for hexagon, which means they have six sides. Hex nuts are also known as: 

 finished hex nuts, hex full nuts. 

 Lock washers may used with hex nuts
.

Hex nut size refers to its nominal thread diameter. Typically, sizes range from 1/4" to about 2 1/2". Size is specified in inches, usually fractional rather than decimal. Table 1 lists width across flats and across corners, and thickness.

Width across flats, which is wrench size, ranges from 1.50 to 1.75 times the nominal hex nut size and thickness is 0.850 to 0.875 times the size. Nuts that are 5/8" and smaller are double (top and bottom) chamfered (beveled); larger sizes may be double chamfered or have a washer face bearing (bottom) surface and a chamfered top.

To ensure full thread engagement with the hex nut, bolts/screws should be long enough to allow at least two full threads to extend beyond the nut face after tightening. Conversely, there should be two full threads exposed on the head side of the nut to make sure the nut can be properly tightened.

Always follow the manufacturer's recommendations regarding nut reuse, thread lubricants/locking compounds and torque values.

It is advisable to match materials and finishes of hex nuts, washers and bolts/screws. When using hot dipped galvanized bolts, always use hot dipped galvanized nuts, which are tapped oversize (threaded larger than normal) to accommodate the thick zinc coating on the bolts (using a galvanized nut on a non-galvanized bolt will result in an unacceptably loose fit and using a plain finish or zinc plated nut on a hot dip galvanized bolt will result in a fit that is much too tight).

Stainless steel hex nuts and bolts/screws used together are susceptible to thread galling and seizing. While it may not be completely preventable, it can be substantially reduced. A thread lubricant is the most effective method. Alternatively, stainless steel alloys having different hardnesses—like a 316 nut and a 304 bolt—have less tendency to gall.

 

Refer to ASME B18.2.2 for specifications relating to hex nuts.

Operation

 

Deflecting under a load, a spring washer is very much like a compression spring. As such, the deflection rate of a wave washer is conditional of the washer's dimensions and materials. Thicker, taller spring washers can sustain more load. When under stress, the raised irregularities of the disc spring flatten to a predetermined degree. Spring washers are either under static or dynamic load. In a static load application, the basic function of the washer is to retain load and the elastic load rating of the washer material may be exceeded. For a dynamic load, the washer functions as a flexing spring and the yield limit must not be exceeded or permanent disfiguration will occur.

 

Spring washers undergo elastic deformation which is reversible and is determined by the material of construction. If the washer is overstressed or near the end of its cycle life, it will experience plastic deformation where some of its deflection is irreversible; this is the first sign of washer fatigue.

 

 

Spring washers have a small footprint and are valued in small machines where a coil spring would be unsuitable. Spring washers can also deflect in a linear, progressive, or regressive means and these devices show a symmetrical deflection around the washer's axis. Spring washers can be stacked to create spring sets or series where deflection and load capacity can vary without materially affecting the forces involved. 

Production

 

 

Production methods of spring washers include stamping, machining, hot forged, rolled, or some combination of these. The following infographic explains common production protocol for spring washers according to material and application requirements.

 

Specifications

 

Washer Dimensions

 

Dimensions of a spring washer are critical to its successful implementation since they are valued for their small size. Like all springs, their dimensions also change depending upon the deflection.

 

• Outer diameter (OD) is the straight-line width across the washer to its furthest edges.
• Inner diameter (ID) is the width across the bored hole of the washer.
• Diameter across slots (DAS) is the measurement of the washer minus the sloped flanges; this is only applicable in belleville washers and may be the same as the inner diameter.
• Diameter of center rotation (DCR) is distance between the center points of the washer flanges. It is essentially the pitch of the washer.
• Cone height (CH) is the measurement of the washer between its lowest and highest points while at rest. This should never be more than 40% of the plate thickness
• Plate thickness (T) is the width of the material used for the washer's construction.
• Washer envelope is the space allocated for a washer's deflection, as the washer's diameters enlarge when under load.
