For the most up to date information on 80/20 products visit 8020.net 363 Fastening Methods FASTENERS Slide-In Economy T-Nut - Offset Thread Part Description: The slide-in economy T-nut with offset thread is a cost-effective fastening method available with options in size, material, and nish. It loads from the prole ends and has a pilot thread projection that adds additional threading for increased strength. The offset thread of the slide-in economy T-nut creates clean connections, making it ideal for corner connections because the T-nut doesn't extend beyond the length of the prole. This T-nut is available in a double (pg. 364) or triple (pg. 365) conguration. For information on 80/20 screw and bolt offerings for the slide-in economy T-nut with offset thread refer to pages beginning on 385. Tip: Position the pilot projection down in the T-slot to avoid an uneven connection or crashing. 1 2 Part No. Series Style Material Grade Finish A B C D (Thread) E F Weight 3676 Style 1 Stainless-Steel 304 Stainless Stainless .625" .187" .380" 10-32 .030" .124" .005 lb 3278 Style 1 Steel 1010 Black Zinc .984" .281" .638" 5/16-18 .080" .222" .020 lb 3778 Style 1 Steel 1010 Bright Zinc .984" .281" .638" 5/16-18 .080" .222" .009 lb 3838 Style 1 Steel 1010 Bright Zinc .984" .281" .638" M8 X 1.25 .080" .222" .009 lb 3678 Style 1 Stainless-Steel 304 Stainless Stainless 1.113" .281" .638" 5/16-18 .080" .222" .027 lb 25-1941 Style 2 Steel 1010 Bright Zinc 15.87 mm 4.75 mm 11.00 mm M4 x 0.7 .76 mm 3.14 mm .0027 kg 25-1951 Style 2 Steel 1010 Bright Zinc 15.87 mm 4.75 mm 11.00 mm M5 x 0.8 .76 mm 3.14 mm .0024 kg 30-1961 Style 1 Steel 1010 Bright Zinc 20.60 mm 5.00 mm 13.00 mm M6 x 1.0 1.27 mm 4.44 mm .0056 kg 40-1981 Style 1 Steel 1010 Bright Zinc 24.99 mm 7.14 mm 16.19 mm M8 x 1.25 2.03 mm 5.64 mm .0092 kg 40-3278 Style 1 Steel 1010 Black Zinc 24.99 mm 7.14 mm 16.19 mm 5/16-18 2.03 mm 5.64 mm .0090 kg D C B A E F D B A C E F Style #1 Style #2 30 Series 25 Series 10 Series 15 Series Metric Fractional 40 Series
