TORQUE ADAPTERS For use with torque wrenches where the type of fastener, clearance, and obstructions dictate the use of a wrench adapter versus a standard socket.

FRDHM17 Thicker Construction than competitive models for strength Center-to-Center Length on adapter for easy torque calculations 12-Point Torque Adapters Torque adapters get into tighter areas where standard sockets cannot reach. Manufactured from special alloy steel, precision forged and heat treated for optimum strength and durability, Snap-on's larger torque adapter sizes are forged thicker than competitor's models for strength when you need it. The double hex (12-point) configuration allows the socket to engage a single hex fastener every 30° rather than every 60°, allowing for better access in restricted areas. And unlike competitor's offerings, these high-strength adapters are made with pride in the USA, insuring the finest quality and durability. 3/8" DRIVE SAE Stock No. FRDH101 FRDH121 FRDH141 FRDH161 FRDH181 FRDH201 FRDH221 FRDH241 FRDH281 FRDH301 Size 5/16" 3/8" 7/16" 1/2" 9/16" 5/8" 11/16" 3/4" 7/8" 15/16" Working Torque 190 in. lbs. 420 in. lbs. 500 in. lbs. 710 in. lbs. 1,050 in. lbs. 1,400 in. lbs. 1,400 in. lbs. 1,400 in. lbs. 2,000 in. lbs. 2,706 in. lbs. 1/4" DRIVE SAE Stock No. TRDHL81 TRDHL101 TRDHL121 TRDHL141 Size 1/4" 5/16" 3/8" 7/16" Working Torque 176 in. lbs. 220 in. lbs. 484 in. lbs. 560 in. lbs. 3/8" DRIVE METRIC Stock No. Size FRDHM8 FRDHM10 FRDHM12 FRDHM13 FRDHM14 FRDHM15 FRDHM16 FRDHM17 FRDHM18 FRDHM19 FRDHM21 8 mm 10 mm 12 mm 13 mm 14 mm 15 mm 16 mm 17 mm 18 mm 19 mm 21 mm 1/4" DRIVE METRIC Stock No. TRDHM6 TRDHM7 TRDHM8 Size 6 mm 7 mm 8 mm Working Torque 212 in. lbs. 420 in. lbs. 690 in. lbs. 720 in. lbs. 1,050 in. lbs. 1,200 in. lbs. 1,400 in. lbs. 804 in. lbs. 1,400 in. lbs. 1,400 in. lbs. 2,000 in. lbs.

Precise, radial spline teeth engage the fastener teeth over a wider area to minimize stress Low Profile Splines Available for limited clearance fasteners FRESL28 SRES24 Center-to-Center Length on adapter for easy torque calculations 12-Point Spline Torque Adapters Snap-on ® spline wrenching tools have been developed to service high tensile strength spline nuts and bolts widely used on both military and commercial aircraft. Precise, radial spline teeth engage the fastener teeth over a wider area to minimize stress, and allow application of high torque to reduce risk of damage to the fastener or to the tool. Chrome tools comply with Military Spec. MS-33787 and MIL-W-89823. The unique spline wrenching configuration can also be used on ordinary six- and 12-point fasteners with an advantage similar to the Snap-on Flank Drive ® wrenching system. 1/2" DRIVE SPLINE Stock No. SRES18 SRES20 SRES22 SRES24 SRES26 SRES28 SRES30A Size #18 - 9/16" #20 - 5/8" #22 - 11/16" #24 - 3/4" #26 - 13/16" #28 - 7/8" #30 - 15/16" Working Torque 2,275 in. lbs. 2,450 in. lbs. 2,975 in. lbs. 3,500 in. lbs. 4,410 in. lbs. 4,900 in. lbs. 6,000 in. lbs. 3/8" DRIVE LOW PROFILE SPLINE Stock No. FRESL24 FRESL28 Size #24-3/4" #28-7/8" Working Torque 465 in. lbs. 605 in. lbs. 3/8" DRIVE SPLINE Stock No. FRES7 FRES8 FRES9 FRES10 FRES12 FRES14 FRES16 FRES18 FRES20 FRES22 FRES24 Size #7 - 7/32" #8 - 1/4" #9 - 9/32" #10 - 5/16" #12 - 3/8" #14 - 7/16" #16 - 1/2" #18 - 9/16" #20 - 5/8" #22 - 11/16" #24 - 3/4" Working Torque 140 in. lbs. 195 in. lbs. 220 in. lbs. 250 in. lbs. 515 in. lbs. 875 in. lbs. 1,575 in. lbs. 1,750 in. lbs. 1,750 in. lbs. 1,750 in. lbs. 1,750 in. lbs. 16
