Lag/Drive Screws

All MPS Lag Screws have rolled threads. Below the head is an upset shoulder with the same outside diameter as the threads to provide a snug fit in hardware mounting holes.

Fast Lags (FX) are easily installed using power tools and able to replace all the below traditional lags. Fast Lag Screw Informational Flyer

Gimlet point Lag Screws are installed with a wrench.

Fetter drive and twist drive lag screws can either be wrenched or driven like a nail for speedier installation without sacrificing any of the holding strength of regular gimlet point lag threads.

Twist drive lags are furnished with a drive point for additional starting ease and accuracy. This feature is also available on most sizes of Fetter Drive lags.

Material: Hot Dip Galvanized Steel

Square head lag screws conform to Bellcore specification 6337
