Self-retaining speed nuts, also known as self retainers and spring clips, are the only fastening devices that provide a compensating thread lock as well as a self-energizing spring lock. Two distinct forces are exerted on the fastening screw as the self retaining speed nut is tightened.
This makes them preferred by assemblers among self retainers available. Ideal for blind assembly or hard-to-reach installation, the self retaining speed nuts come in numerous standard designs and special variations. Contact Bolt Products to request a quote for self retaining speed nuts today.

Use the phrase "Lefty loosey, Righty tighty" to help remember which direction to twist the nut or bolt to loosen or tighten it.
Bolts are typically used to fasten two or more objects together through pre-drilled holes. Washers are used to strengthen the connection by distributing the force that is being applied by the bolt over a broader area. Specialty washers are also available. Lock washers, for example, help prevent accidental loosening of the bolt. Nuts are threaded onto the bolt to tighten the connection and, like washers, come in a variety of types for a variety of applications.
Determine the correct size and type of bolt, nut and washer for your application. This will depend on the type of connection being made, the materials being used, the strength of the bolt, standards and regulations for the application and a variety of other factors.
Place the first washer on the shaft of the bolt. If a lock washer is required, it will be placed on the bolt followed by a second standard washer. Align the holes for the joint you are connecting and push the shaft of the bolt through them. The washers should be pressed between the head of the bolt and the material of the joint.
Place the second washer, or set of washers, on the portion of the shaft of the bolt that is sticking out from the joint.
Thread the nut onto the shaft of the bolt by twisting clockwise. Hand-tighten the nut so that it is pressed against the washers. Grant is a writer and a consultant for in the areas of leadership, team-building, and communication skills.

This is the most common thermocouple type that provides the widest operating temperature range. Type K thermocouples generally will work in most applications because they are nickel based and have good corrosion resistance.
Positive leg is non-magnetic Yellownegative leg is magnetic Red. Traditional base-metal choice for high temperature work. Vulnerable to sulfur attack refrain from exposing to sulfur-containing atmospheres. Perform best in clean oxidizing atmospheres. Not recommended for use under partially oxidizing conditions in vacuum, or when subjected to alternating cycles of oxidization and reduction.
Type K was specified at a time when metallurgy was less advanced than it is today, and consequently characteristics vary considerably between samples. Type K thermocouples usually work in most applications as they are nickel based and exhibit good corrosion resistance.
It is the most common sensor calibration type providing the widest operating temperature range. This type of thermocouple should be protected with a suitable metal or ceramic protection tube, especially in reducing atmospheres. In oxidizing atmospheres, such as electric furnaces, tube protection is not always necessary when other conditions are suitable; however, it is recommended for cleanliness and general mechanical protection.
Type K will generally outlast Type J because the JP wire rapidly oxidizes, especially at higher temperatures. Deviations in the alloys can affect the accuracy of thermocouples.
However, deviations between thermocouples coming from the same production are very small and a much higher accuracy can be achieved by individual calibration. A special grade of Type K is available that can maintain special limit accuracy up to ten times longer than the regular grade. This Thermocouple has the highest EMF output per degree of all recognized thermocouples.
Often used as a differential measurement since only copper wire touches the probes. Type T is very stable and is used in a wide variety of cryogenic and low temperature applications. Type N Nicrosil? Sensitivity is about 39? Type N was developed to overcome several problems inherent in Type K thermocouples. Type N has also been found to be more stable than Type K in nuclear environments.
Also easily contaminated, and damaged by reducing atmospheres. The same protective measures as shown above apply to type B Thermocouples.
U-Clips & Nuts
Easily contaminated. Reducing atmospheres are particularly damaging. Type S should be protected with gas tight ceramic tubes, a secondary tube of porcelain and silicon carbide or metal outer tubes, as conditions require. Type R should by protected in a similar fashion as Type S.
Has the fastest response time ideal for measuring rapid temperature changes. Clear coating on most models provides a humidity barrier for the thermocouple. Do not use with corrosive fluids or atmospheres.Search Advanced Search. Our custom fasteners have enjoyed great success supplying all types and sizes of businesses in most sectors of industry. Contact Apex Fasteners with your hardware requirements. Authorized Distributor for: See List. Nut Retainers, also known as Cage Nuts, combine the best advantages of spring steel fasteners with the high strength of a multi-threaded nut.
They snap readily into bolt-receiving position at panel edges or center panel locations and retain themselves in place. Their application does not require special tools or skills. They can be applied at any convenient spot along the assembly line. The nut floats within the spring steel cage more than enough to offfset normal hole misalignment.
They are excellent fasteners for blind location assemblies. They lack the floating properties of a Cage Nut but provide increased thread engagement over the normal U-Nut or J-Nut. Nut retainers are available in a clear zinc -3B or black phosphate -4 finish. Contact Us. Write Review. Designed by Pope Productions. Parse Time: 0.Fasteners come in many different forms. Scroll down to learn about many different types of nuts, bolts and screws!
Screws use their threads to provide their own holding power. The terms in the industry are commonly mixed so sometimes you will see something that is called a screw or a bolt that is actually the opposite.
Example: Lag Bolts and Lag Screws are the same thing. We have broken them down according to their true definition. The square section under the head grips into the part being fastened preventing the bolt from turning when the nut is tightened.
Shop Carriage Bolts. Hex tap bolts, hex cap screws, trim head hex cap screws, and hex serrated flange bolts fall under this category. They share a hexagonal head and are driven with a wrench. Referred to as both bolts and screws. Shop Hex Head Bolts. A machine screw is a screw or bolt with a flat point. Available in a variety of drive types and heads, they fit a wide variety of applications. Often driven into tapped holes.
Shop our Machine Screws. Shoulder bolts also known as shoulder screws or stripper bolts are machine screws with a shoulder between the thread of the screw and the head of the part. Once installed, the non-threaded portion extends out of the surface of the application site, allowing the bolts to act as dowels or shafts for moving parts.
They can be installed by hand or with a socket Allen driver. Shop Shoulder Bolts. Socket cap screws are available in button socket, button flange socket head, flat socket, and socket cap. Driven with a socket wrench or a hex Allen key. The term socket head cap screw typically refers to a type of threaded fastener whose head diameter is nominally 1. Shop our Socket Cap Screws.
