Product Overview:

Anchor nuts are essential matching fasteners for self-drilling anchor bolts, extensively applied in slope stabilization, tunnel surrounding rock support, mine roadway reinforcement, foundation pit support，and geotechnical anchorage engineering. It compresses the plate to closely fit the rock surface, constrains rock mass deformation and prevents rock collapse and crack expansion. Complete specifications match R25, R32, R38, R51 and other mainstream anchor bolt models, with stable mechanical performance adapting to damp underground, high-pressure and corrosive mine environments.

Core Advantages:

1.High-precision thread fit 
Inner threads are rolled with high precision, consistent tooth shape and high matching degree with anchor bolt external threads. Free of thread slipping, sliding tooth and locking failure under dynamic rock pressure and long-term sustained load to guarantee anchorage safety.

2.Standardized complete specifications & test certification 
Full-size series matching mainstream hollow anchor bolts (R25/R32/R38/R51 etc.). Products can provide MTC material inspection reports to meet the inspection requirements of engineering bidding and project acceptance.

3.Uniform force bearing surface 
Flat bottom contact surface realizes even pressure transfer onto the bearing plate. Disperse local stress concentration, lower the risk of plate deformation and surrounding concrete/rock cracking under preload force.

4.Flexible customizable service 
Support non-standard customization of nut height, outer circle size, wall thickness and special threads based on customer drawings; stable mass production and punctual delivery for bulk export orders.
