Cable Tray Conduit Wall Plastic Expansion Screw Anchor Nylon PA6 M5 Multi-Purpose Electrical Fastener Kit
Product Description
The Nylon Plastic Expansion Screw Cable Tray Conduit Bracket Fastener is a versatile multi-purpose fastening solution specifically designed for electrical cable trays, PVC conduit straps, metal trunking brackets, and various electrical installation support hardware on brick, concrete, hollow block, and drywall substrates. Each complete set contains an 8mm diameter PA6 nylon expansion plug pre-matched with an M5 x 50mm zinc-plated steel screw, delivering universal compatibility across diverse electrical installation scenarios.
The installation follows the proven plastic expansion principle: select the correct drill bit matching the 8mm plug diameter, drill an 8mm hole to 60mm depth at each cable tray or conduit bracket mounting position, insert the nylon plug until the collar sits flush with the wall surface, position the cable tray bracket or conduit strap, then drive the M5 screw through the bracket into the plug. As the screw advances to full depth, the cone-shaped tail section forces the nylon body to expand radially outward against the drill hole wall, using the friction generated by the screw spreading the plug to create a tight locking grip in the substrate. The nylon plug body is completely rust-proof and resistant to moisture absorption, ensuring reliable long-term fastening performance in basements, utility rooms, outdoor electrical enclosures, and other environments where metal anchors would eventually corrode.
Designed for the cost-conscious electrical contractor and volume installer, this fastener is available in economy bulk pack quantities with competitive wholesale pricing. The 50mm extended plug body provides a deep expansion zone that delivers consistent holding power across multiple substrate types - from solid concrete walls in commercial electrical rooms to hollow brick and drywall partitions in residential wiring projects. The universal M5 screw head style is compatible with standard Phillips and Pozidriv screwdrivers used on every electrical installation site, requiring no special tools or bits for installation.
Features
Multi-Purpose Tray Anchor
The 8mm plug with M5 screw combination is engineered to securely mount the most common sizes of PVC and metal cable trays, conduit straps, and trunking brackets found in residential, commercial, and light industrial electrical installations. One fastener type covers multiple electrical mounting applications, reducing the variety of anchors electrical contractors need to stock and carry to each job site.
Cost-Effective Bulk Fastening
Available in cost-optimized bulk quantities of 500, 1000, or 5000+ pieces per carton, this fastener delivers exceptional per-unit value for electrical contractors, wholesale distributors, and volume purchasers. The competitive pricing combined with professional-grade PA6 nylon and zinc-plated steel construction makes it the practical choice for large-scale electrical installation projects where hundreds or thousands of anchor points are required.
All-Environment Plastic Plug
The 100% rust-proof PA6 nylon plug functions reliably in damp basements, humid utility spaces, outdoor electrical enclosures, and areas subject to occasional water exposure where traditional metal anchors would eventually corrode and fail. The nylon material never rusts, never swells from moisture absorption, and maintains its full mechanical expansion properties across the complete operating temperature range from -40°C to +80°C, providing dependable anchoring in any indoor or outdoor electrical installation environment.
