While some might interchange screws and bolts, there are some differences. Screws An externally threaded fastener that has thread form which prohibits assembly with a nut having a straight thread of multiple pitch length is a screw. (Example: wood screws, tapping screws.) A screw is a fastener capable of being inserted into holes in assembled parts, of mating with a preformed internal thread or forming its own thread, and of being tightened or released by torquing the head. Bolts An externally threaded fastener which is prevented from being turned during assembly and which can be tightened or released only by torquing a nut is a bolt. (Example: round head bolts, track bolts, plow bolts.) Internal threads refer to those on nuts and tapped holes, while external threads are those on bolts, studs, or screws. Threads can be produced by either cutting or rolling. Cut threading is a process by which steel is cut away from a round bar of steel to form the threads. Advantages of Cut Threading: Few limitations with regard to diameter and thread length All specifications can be manufactured with cut threads Disadvantages: Longer labor times The weakest area of any mechanical fastener is the minor diameter of the threads. Since the thread dimensions of a cut thread and rolled thread fastener are identical, there is absolutely no difference in strength. However, cut threading interrupts the natural grain structure of the round bar whereas roll threading reforms it Advantages of Roll Threading: Shorter labor times Weighs less than its Cut threaded bolts thereby reducing the cost of the steel, plating, freight, and any other costs associated with the fastener that are based on weight Cold working makes threads more resistant to damage during handling Rolled threads are often smoother. The distance measured parallel to the thread axis, between corresponding points on adjacent threads, is the thread pitch. Unified screw threads are designated in threads per inch. This is the number of complete threads occurring in one inch of threaded length. Metric thread pitch is designated as the distance between threads (pitch) in millimeters ADDITIONAL SERVICES Program Management Proprietary Applications & Development 3PL & Supplier Consolidation Kitting & Assembly Compliance Management Diversified Sourcing & Risk Mitigation REQUEST A QUOTE CONTACT INFO First Name Last Name Company / Organization Phone Number Email Company Address Select Afghanistan Åland Albania Algeria American Samoa Andorra Angola Anguilla Antarctica Antigua and Barbuda Argentina Armenia Aruba Australia Austria Azerbaijan Bahamas Bahrain Bangladesh Barbados Belarus Belgium Belize Benin Bermuda Bhutan Bolivia Bonaire Bosnia and Herzegovina Botswana Bouvet Island Brazil British Indian Ocean Territory British Virgin Islands Brunei Bulgaria Burkina Faso Burundi Cambodia Cameroon Canada Cape Verde Cayman Islands Central African Republic Chad Chile China Christmas Island Cocos [Keeling] Islands Colombia Comoros Cook Islands Costa Rica Croatia Cuba Curacao Cyprus Czech Republic Democratic Republic of the Congo Denmark Djibouti Dominica Dominican Republic East Timor Ecuador Egypt El Salvador Equatorial Guinea Eritrea Estonia Ethiopia Falkland Islands Faroe Islands Fiji Finland France French Guiana French Polynesia French Southern Territories Gabon Gambia Georgia Germany Ghana Gibraltar Greece Greenland Grenada Guadeloupe Guam Guatemala Guernsey Guinea Guinea-Bissau Guyana Haiti Heard Island and McDonald Islands Honduras Hong Kong Hungary Iceland India Indonesia Iran Iraq Ireland Isle of Man Israel Italy Ivory Coast Jamaica Japan Jersey Jordan Kazakhstan Kenya Kiribati Kosovo Kuwait Kyrgyzstan Laos Latvia Lebanon Lesotho Liberia Libya Liechtenstein Lithuania Luxembourg Macao Macedonia Madagascar Malawi Malaysia Maldives Mali Malta Marshall Islands Martinique Mauritania Mauritius Mayotte Mexico Micronesia Moldova Monaco Mongolia Montenegro Montserrat Morocco Mozambique Myanmar [Burma] Namibia Nauru Nepal Netherlands New Caledonia New Zealand Nicaragua Niger Nigeria Niue Norfolk Island North Korea Northern Mariana Islands Norway Oman Pakistan Palau Palestine Panama Papua New Guinea Paraguay Peru Philippines Pitcairn Islands Poland Portugal Puerto Rico Qatar Republic of the Congo Réunion Romania Russia Rwanda Saint Barthélemy Saint Helena Saint Kitts and Nevis Saint Lucia Saint Martin Saint Pierre and Miquelon Saint Vincent and the Grenadines Samoa San Marino São Tomé and Príncipe Saudi Arabia Senegal Serbia Seychelles Sierra Leone Singapore Sint Maarten Slovakia Slovenia Solomon Islands Somalia South Africa South Georgia and the South Sandwich Islands South Korea South Sudan Spain Sri Lanka Sudan Suriname Svalbard and Jan Mayen Swaziland Sweden Switzerland Syria Taiwan Tajikistan Tanzania Thailand Togo Tokelau Tonga Trinidad and Tobago Tunisia Turkey Turkmenistan Turks and Caicos Islands Tuvalu U.S. Minor Outlying Islands U.S. Virgin Islands Uganda Ukraine United Arab Emirates United Kingdom United States Uruguay Uzbekistan Vanuatu Vatican City Venezuela Vietnam Wallis and Futuna Western Sahara Yemen Zambia Zimbabwe Country City Select Alabama Alaska Alberta American Samoa Arizona Arkansas British Columbia California Colorado Connecticut Delaware District Of Columbia Federated States Of Micronesia Florida Georgia Guam Hawaii Idaho Illinois Indiana Iowa Kansas Kentucky Louisiana Maine Manitoba Marshall Islands Maryland Massachusetts Michigan Minnesota Mississippi Missouri Montana Nebraska Nevada New Brunswick New Hampshire New Jersey New Mexico New York Newfoundland North Carolina North Dakota Northern Mariana Islands Northwest Territories Nova Scotia Nunavut Ohio Oklahoma Ontario Oregon Palau Pennsylvania Prince Edward Island Puerto Rico Quebec Rhode Island Saskatchewan South Carolina South Dakota Tennessee Texas Utah Vermont Virgin Islands Virginia Washington West Virginia Wisconsin Wyoming Yukon Territory State Zip Code QUOTE INFORMATION What kind of services are you interested in? 3PL & Supplier Consolidation Compliance Management Diversified Sourcing & Risk Mitigation Kitting & Assembly Program Management Proprietary Applications & Development What kind of products do you need help with?
