1/4-20x1/2 Blind Cert

• Fasten in thin walls or blind holes
• Ideal for use in plastic-to-metal and other dissimilar materials
• Provides seal-tight applications and resists air or liquid leakage at the assembly joint
• Compressed rubber nut absorbs shock to reduce vibration
• Material: Neoprene body with a brass nut
Directions For Use:
Hollow Walls:
1. Insert in predrilled hole with flange against outer surface.
2. Part to be assembled to surface is placed against flange of fastener and secured by machine screw engaging fastener's brass nut.
3. As machine screw is tightened, neoprene body is compressed and expanded, forcing it tightly into screw threads and against surface of thin-wall material.

Solid Walls:
Follow same steps as in hollow wall fastening. As screw is tightened, body of fastener expands tightly against walls of hole, giving secure, dependable fastening.
