'Well Nut', a flanged neoprene bushing with a captive brass nut, is designed to provide a shock and vibration resistant fixing for engineering structures. This demountable blind screw anchor is suitable for applications of many kinds in many conditions, in materials from thin gauge metals to plastic sheet up to 16.5mm thick; a high rate of radial expansion even allows use in blind holes in solid materials.

Benefits:

• Access needed to only one side of the workpiece
• Used with standard metric machine screws
• Fastens in blind, burr-free holes
• Can be used in closed end holes
• Will not mar prefinished surfaces
• Helps seal out ambient moisture
• Absorbs noise
• Electrically isolating
• Dampens vibration and shock
• Helps prevent galvanic corrosion
• Ideal for metal-to-plastic and other mixed material assemblies
• Resistant to ozone and weathering in outdoor conditions
• Suitable for marine applications
• Removable and reusable
• Snap-in feature to facilitate assembly line use
