The set screw bites into the steel creating a very strong mechanical fastening, suitable for industrial shelving. <\/span>\n        <\/div>\n<div style=\"background-color: #f8f9fa; border-left: 4px solid #fba905; padding: 20px; margin-bottom: 15px; border-radius: 0 6px 6px 0;\">\n            <span style=\"display: block; font-weight: bold; color: #101828; margin-bottom: 8px;\">Can they be used outdoors?<\/span><br \/>\n            <span style=\"color: #555;\">Perfectly. If both tubes and connectors are made of galvanized steel, they resist corrosion and weathering as well or better than a welded and painted structure. <\/span>\n        <\/div>\n<div style=\"background-color: #f8f9fa; border-left: 4px solid #fba905; padding: 20px; margin-bottom: 15px; border-radius: 0 6px 6px 0;\">\n            <span style=\"display: block; font-weight: bold; color: #101828; margin-bottom: 8px;\">Are they suitable for any tube?<\/span><br \/>\n            <span style=\"color: #555;\">No, they must be tubes of the specific diameter or dimension for the connector (e.g. 30&#215;30 or 40&#215;40 square tube). Precision is key to the grip. <\/span>\n        <\/div>\n<div style=\"background-color: #f8f9fa; border-left: 4px solid #fba905; padding: 20px; margin-bottom: 15px; border-radius: 0 6px 6px 0;\">\n            <span style=\"display: block; font-weight: bold; color: #101828; margin-bottom: 8px;\">Do they loosen with vibration?<\/span><br \/>\n            <span style=\"color: #555;\">If tightened to the recommended torque, they are very difficult to loosen. For high vibration machinery, chemical threadlockers can be used for extra security. <\/span>\n        <\/div>\n<div style=\"background-color: #f8f9fa; border-left: 4px solid #fba905; padding: 20px; margin-bottom: 15px; border-radius: 0 6px 6px 0;\">\n            <span style=\"display: block; font-weight: bold; color: #101828; margin-bottom: 8px;\">Can I disassemble and reuse the parts?<\/span><br \/>\n            <span style=\"color: #555;\">This is one of its great advantages. You can disassemble a table and use the same parts and tubes to build a shelf years later. <\/span>\n        <\/div>\n<div style=\"background-color: #f8f9fa; border-left: 4px solid #fba905; padding: 20px; margin-bottom: 15px; border-radius: 0 6px 6px 0;\">\n            <span style=\"display: block; font-weight: bold; color: #101828; margin-bottom: 8px;\">Is it more expensive than welding?<\/span><br \/>\n            <span style=\"color: #555;\">The parts have a cost, but you save the welding machine, gas, electrodes and skilled labor time, so the final cost is usually lower.<\/span>\n        <\/div>\n<\/p><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>How to join metal pipes without welding or threading Metalworking has historically been reserved for professionals due to the complexity of welding.
