Technical Information

When installing machine screw anchors, many technical requirements such as anchor size, anchor length, and hole size must be considered. These machine screws meet industry standards and come in a wide range of sizes. Concrete machine screw anchors can be used when working with concrete weighting up to 5860lbs. Machine screws can be used in variable conditions and are highly corrosive resistant. Fixtures being held by these anchors can also be removed and replaced without losing holding value.

Anchor Size	Anchor Length	Hole Size	Pullout 6,000 PSI Concrete
#10	5/8”	3/8”	1180 lb.
5/16”	1”	5/8”	2200 lb.
1/4”	7/8”	1/2”	1340 lb.
3/8”	1-1/4”	3/4”	2840 lb.
1/2”	1-1/2”	7/8”	3120 lb.
5/8”	1-3/4”	1-1/8”	4940 lb.
3/4”	2-1/4”	1-1/4”	5860 lb.
Values shown are average ultimate values and are offered only as a guide and are not guaranteed. A safety factor of 4:1 or 25% is generally accepted as a safe working load. Reference should be made to applicable codes for the specific working ratio. Minimum embedment for satisfactory anchor performance is 4-1/2 bolt diameters. Deeper embedments will yield higher tension and shear capacity.
