UTT7401 square washer is a general-purpose matching fastener for strut channel systems. Adopting durable carbon steel as raw material, it is equipped with three mainstream surface treatments to adapt to different indoor, humid and outdoor working environments. This product features a square structure with a large bearing area, which can effectively disperse pressure, prevent bolt loosening and component slippage during use.
It comes with four regular standard sizes for common bolt specifications, and supports personalized size customization to meet special construction demands. Widely matched with strut channels, pipe clamps and various bolt assemblies, it is an essential accessory for pipeline support, steel structure and electromechanical installation projects.
Core Function: Fasten components and hardware firmly onto strut channels, disperse load and prevent loosening
Raw Material: High-strength carbon steel
Surface Finish: Black finish / Electro-galvanized / Hot-dip galvanized (HDG)
Standard Sizes: 3/8", 1/2", 5/8", 3/4"
Customization Service: Custom sizes are available on request
Package Specification: Weight per 100 pieces varies by size

1.Select the UTT7401 square washer of corresponding size according to the bolt diameter.
2.Sleeve the washer onto the bolt and place it between the bolt head/nut and the surface of strut channel.
3.Align the mounting position to ensure the washer fully covers the stress area.
4.Tighten the bolt and nut evenly to complete the fastening work.
5.Check the tightness to confirm no deviation or slippage.
1.All products comply with general fastener manufacturing standards for strut channel systems.
2.Black, electro-galvanized and hot-dip galvanized finishes all meet international anti-corrosion and surface treatment requirements.
3.Every product passes dimensional inspection and appearance test before leaving the factory.
Black finish for cost-effective indoor projects; electro-galvanizing for conventional humid environments; hot-dip galvanizing for outdoor and heavily corrosive conditions.
Large square bearing surface disperses local pressure, protecting strut channels and extending service life.
Four standard sizes match most common bolt specifications, covering most conventional installation demands.
Supports non-standard size production to satisfy special engineering requirements.
